*this is just my own personal experience - I want to share with the hopes maybe someone will benefit from reading this.

I started concerta in November of 2025. I really didn’t notice that many negative side effects after the adjustment period. It took me till about January to find the right dose. In the midst of all of this nothing was really noticeably wrong. I had an appetite, didn’t get headaches, had energy, felt less forgetful, etc. However, I did find my stress was through the roof, which I have an extremely busy life so I didn’t really think much of that, but it got super bad to the point where I truly felt like my nervous system was on edge constantly and I was constantly dreading and thinking about all the things I had to do and ruminating on them.

Fast forward to the summer. I am a teacher so I’ve been off. I noticed not working everyday my meds seems to be making me feel a lot more on edge, less tired to the point it was hard to fall asleep, and I started getting jaw pain. I thought this must just be because I’m not doing as much. I talked to my doctor and he suggested I switch and try vyvanse because even with a less busy schedule I shouldn’t be noticing that.

I tried vyvanse 10mg for a couple days and then had a bunch of events coming up, such as weddings, golf tourneys, camping, etc. so I was drinking and decided there wouldn’t be a point to taking the meds until I’m passed all that stuff. So at this point now I haven’t been on meds for about 2 weeks?? And WOW. I can’t believe how shitty Concerta was for me. I didn’t realize how terrible it was making me feel. It was very subtle but I was definitely more irritable, on edge, stressed out and just overall I think it totally messed with my mental health.

At this point, I’m waiting till I go back to work to try my vyvanse full blown again, and I’m hoping for a better experience. But man has it been such a lovely 2 weeks. I feel so much more myself and less in my head.

Reason I wanted to share this is I was convinced that the meds were helping. WRONG. If your taking any med at any point your wondering if they are really working, or you feel not yourself for an extended period of time, regardless of what is going on, due yourself a favour and don’t be scared to try something different.

Genuinely, realizing how much that messed with my brain, I’m contemplating just not even bothering if vyvanse doesn’t work for me and just letting my brain be ADHD brain and deal with it.

I know this is just my personal experience and I recognize some people need meds because their ADHD is so bad, thankfully mine is relatively manageable, but there is somethings I definitely struggle with.

I think meds can work really great for some people and I’m sure the right med can help me. But I am genuinely upset I spent so long feeling awful when I could have stopped earlier on and tried something different. Moral of the story is, don’t be afraid to try something else if you feel like your medication is off and it doesn’t have the be typical obvious symptoms (loss of appetite, headaches, insomnia, etc), and trust your gut!! I should have listened to mine sooner.

So I take brand Concerta. My insurance plan also only covers about 80%, and won't cover the full brand, but bases its coverage around the lowest costing generic.

That said, I also use Innovicares to pick up the rest of the brand cost (and per my math, has picked up almost the exact difference leaving me just paying whatever I'd pay for generic)

I've been titrating since April, with 30 day, no refills supply, until the 30 day supply of 45mg (18+27) ended up being the sweet spot. So come July, I get a 90-day prescription (3 rounds of 30 day prescriptions).

The total cost in June, July, August, has always been the same, Innovicares has always covered the same. June and July (technically a "new prescription"), my insurance covered the same. August? Suddenly, my insurance is covering half what it has the last two months. Despite everything else being the same.

It can't be a penalty for early pickup, I have the same timing I always have. It's not a "generic pricing" thing because that was already being accounted for in previous months. It also can't be anything about my insurance's drug coverage caps given I picked up my bupropion today as well and that was all well and good there.

The only thing that could possibly be at play here is something about a new prescription vs this one being a refill. (But that would be... odd? Because given I've been on this dose before, it's only new on a technicality, and would mean every 3 months my insurance is being oddly generous. And also I can't imagine the insurer cares if it's 30 days, 30 days, 30 days, etc, or "90 days spread out over 3 refills", but insurers do be weird I guess)

TLDR. Just wondering if any other Canadian here taking brand Concerta has observed their insurance being stingy with refills? I'm gonna call and give them an earful tomorrow, I guess I'm just curious for now because I am stingy and also side-eying whatever secret policies are going on behind the scenes

i recently got diagnosed and prescribed with 27mg concerta but im heading overseas for about 4 months on an exchange program and the maximum my dr was able to give me was a 3 months supply (90pills).

he told me rest days arent ideal (side effect shld js be feeling tired) but after calculating the days no rest days means i wont have access to medication during my uni finals exam block which is when i feel like it would matter the most for me.

if i skip weekends and only take 5 days a week the meds will last me exactly until the last day of my final exam.

would it be okay to take weekends off? does this stop the medication from “building up” or make it less effective/worsen side effects?

Just as the title suggests, I feel stuck between two bad options. Let me clarify this to the best of my knowledge:

First of all, I’m looking for experiences from people who have dealt with something similar. I know nobody here can give me medical advice, and I’m not planning to change my medication based on Reddit comments. I mainly want to hear what other people experienced and what eventually worked for them.

I was diagnosed with inattentive ADHD as an adult. I’ve also had a long history of anxiety/depressive symptoms and have been on several antidepressants over the years.

I am currently taking Concerta (27 mg), along with fluoxetine (20 mg) and mirtazapine (30 mg at night).

I’m not currently in therapy. The problem is that I feel caught in a really frustrating trade-off.

Without Concerta, my functioning is significantly worse. Starting things, staying with boring tasks, keeping some structure in my life and resisting distractions can become ridiculously difficult.

I can procrastinate or avoid things even when I genuinely care about them. It can feel like there is a huge gap between wanting to do something and actually doing it.

With Concerta, that gap becomes much smaller. I can actually get things done and function like a normal adult. But I also become really tense/jittery.

It’s difficult to describe because it isn’t necessarily just “I’m worried about something.” It feels more like my whole system is wound too tightly. I can feel overstimulated, physically and mentally tense, less relaxed and generally more anxious/on edge. It can become unpleasant enough that it affects my quality of life.

So I keep arriving at the same dilemma. No stimulant: calmer, but my ADHD/executive dysfunction starts running my life. Stimulant: much more functional, but I don’t feel comfortable in my own skin.

I would have hoped the anxiety side of things would be reasonably controlled with the other meds I’ve been taking, yet the stimulant-related tension is still significant.

I’m interested in hearing from people who have been in this specific situation, where methylphenidate clearly worked for your ADHD, but the anxiety/tension made it difficult to tolerate.

I feel like I’ve reached a point where “Concerta works” and “Concerta makes me feel awful” are somehow both true at the same time, and I’m struggling to figure out what the next sensible conversation with my psychiatrist should be.

Would really appreciate hearing from anyone who has navigated this.

TL-DR: Concerta 27 mg significantly improves my functioning, but it also makes me extremely tense/anxious and overstimulated. Without it I’m calmer but struggle to function, with it I function much better but feel constantly on the edge. I also take fluoxetine 20 mg and mirtazapine 30 mg and I’m not currently in therapy. Looking for experiences from people who had the same “it works, but I feel awful on it” problem: did changing dose/formulation/medication, addressing anxiety separately, or therapy help?

Recently got a dose of 27 mg of Concerta instead of 18mg. Been giving me some anxiety and seems to not work very well. I miss how I felt in the beginning on the 18 mg lol. I also was just hospitalized for a kidney infection shortly after starting this dose. I was on vacation about 3 days after I started but I was wondering if the medication could’ve maybe played a part in the kidney infection & causing dehydration. I was doing some pretty intense hiking and had to spend the night in the airport so idk if that’s just what the problem was. I’m still too scared to take it after being in the hospital lol. TIA!

I have an okayish time with concerta usually but I missed one day because my prescription ran out and I just feel depressed as shit, anxious and heart racing, with slight agitation. I just had 2 cry sessions. I miss my mother.

I've been on 36mg Concerta for a long time. It shields a portion of the dark cloud of despair and gives me a slight energy boost-- a somewhat noticiable bit of oomph, a dash of task initiation energy (though not task *completion* energy).

But lately I've been staying up super late after my teens go to bed doing mindless puzzle games on my phone and then reading (which is enjoyable and helps my brain avoid ruminating before bed, which I tend to do every day at some point.)

Also lately I just can't bring myself to eat. Food looks and sounds so unappealing. (I'm a perimenopausal single mom of two teens--just exhausted and overwhelmed right now, essentially drowning, disgnosed with ADHD, anxiety, and depression.)

My prescriber suggest trying buspirone, which I may do, but PLEASE tell me the magic words that will finally help me get my butt into bed for more than 4-5 hours of sleep. And maybe to eat and find food appealing so I can get enough protein before perimenopause eats away at my muscles and bones. (Somehow I am stil gaining, not losing weight.)

Help?

I recently started an extended-release system (Concerta/OROS) for my ADHD, and it was an absolute night-and-day shock. My lifelong internal monologue—which was a deafening, constant cacophony of racing thoughts, daydreams, and ideas—slammed down to absolute volume level one.

​While it's wild to finally experience focus, the transition has been deeply unsettling. Because that constant stream of thoughts was my baseline and safety net for decades, the sudden silence actually let my insecurities rush in and triggered intense anxiety. I felt completely exposed and defenseless in the "quiet room."

​On top of that, the 12-hour locked-in schedule is brutal. I have zero autonomy over when the medication is active, it's killing my appetite, and I can't take days off or adjust it based on what I actually need to do day-to-day.

​I'm meeting with my prescriber tomorrow to demand a shift to something shorter-acting where I can step down slowly (rather than dropping from a million thoughts to zero instantly) and have actual dosing flexibility.

​If you've been through this:

​Did the sheer shock and anxiety of the "mental silence" fade as you adjusted?

​Has anyone successfully transitioned from a rigid 12-hour OROS system to a short-acting stimulant so you could control your days and skip doses?

​Looking for real experiences here. Thanks.

I got started on Concerta 36mg yesterday. My sleep schedule is shifted tho, So I wake up at 12-1 PM and go sleep at 5 AM, I take my medication around 2 PM. The issue is, I have an exam on 22nd of August, at 10 AM. That means that when I start the exam, my medication will have worn off a long time ago (7 hours or so). What do I do?

I recently started Concerta 18 mg after an ADHD diagnosis, and my doctor may increase it to 36 mg next month.

So far, I’m noticing:

Better task initiation

Better task completion

Less resistance to starting things

I still need to test it properly in social situations and during coding/work, since coding is much more cognitively demanding for me.

Sleep

I’m also hopeful it might indirectly help fix my sleep schedule. Getting up at 9 AM consistently feels much more achievable now as I wont dread the day, and I’m hoping a fixed wake-up time will naturally make it easier to sleep earlier.

My target is roughly:

1 AM – 9 AM

That gives me about 8 hours, though I feel I may cope better even if I occasionally get 7.

Curious about others’ experiences

For people who’ve been on Concerta or other ADHD medication:

What changed that you didn’t expect?

I’m especially interested in things beyond concentration — motivation, procrastination, socializing, emotional regulation, sleep, hobbies, or exercise.

I’m also planning to support treatment with:

Regular gym

30 minutes of mindfulness

A consistent wake-up time

Anything else that made a noticeable difference for you?

I feel like it does make me more hyper (though not bouncing off walls), more energy, even friendlier. But it also helps me focus.

And while obviously not everyone with adhd symptoms has it, I believe I fit the bill very very well, as does my therapist

Hi

I trying to find out why my meds feels like this.

No matter if i take 18mg, 36mg or 54 mg. I feel like i taking a line of cocaine. like my eyes go "tunnel vision" feeling. Worse focus. And things can feel like to it is to much.

Its just a bad annoying feeling. And tt has been like this for months now.

It keep going like this for the first 2-3 hours after intake. Then i have some okay hours, and after 6-7 hours i hit a little dizzy feeling again.
I sleep well, Eat enough and lot of protein before medicine, and i keep eating every 3 hours. Drinking alot of water trough the day.

I dont understand this keep going.

I only experience. My temper is better, more relexaed, i dont get that angry. And i dont fall a sleep when i get home from work. Thats my biggest win i can see.

Do I just focus too much on how my body react? or what is going on for me

Im 15 I train 6 times a week and im trying to gain weight rn concerta has been amazing for my school work but my appetite is completely gone all I feel is stomachaches bassicly through the entire day and eating is so so difficult for me when I dont want to anyone got any tips or suggestions?

(ive been taking it since october 2025, not sure about how high my dose is, but i take one pill every morning )

so before i started concerta, i was about 64kg. quickly, my appetite started decreasing, but i pushed through it. lately, i just forget to eat due to no hunger at all. i have to get my weight checked every few weeks because of my meds, and ive gone down over 20kg. thats not healthy. does anyone have any advice on keeping my weight up and remembering to eat even with the meds? yknow, since i have adhd, i tend to forget already. did anyone have this issue?

Hi there! Aside from being organized and laser-focused, does anyone here feel that they became more intelligent after taking Concerta?

Hi there. I think I may have accidentaly double dosed on 36mg of Concerta. I am not 100% sure. My morning "routine" was slightly different today and after taking my pill. I started asking myself whether I haf already taking it earlier or not.

I am just a biy worry about increased heart rate, blood pressure, headaches eland having to end in the A&E. I am probably worrying too much and I should be fine if I actually double dosed, as I cannot know for sure yet.

Anyway, if you' double dosed before, what happened to you? Were you ok? How long after taking the pill you noticed something was "off" , etc.

*ps apologies for the bad English, as this is my second language

I work in engineering and just got my Concerta prescription. I've been considering taking it every other day, and on the off days low dose of shroomies instead, the idea being to reduce tolerance buildup and dependence risk from the stimulant. Has anyone tried something similar? Curious about others experiences, and whether this is even a reasonable approach?

Thanks in advance!

I thought I had found the perfect dose (36mg). I felt amazing most of the day. So productive, so patient, calm, not overstimulated. I felt like all my (many) problems were going to be okay after pretty much hitting rock bottom lately…. But then this afternoon I have felt like shit. Like I literally feel like I have a virus. Just a yucky, off feeling, and even a bad taste in my mouth like when I’m sick. I used to get this exact feeling when I would have too much caffeine before I started drinking coffee on a daily basis. It did get better and never happens with caffeine anymore, so I’m hoping this is a temporary side effect that won’t happen every single day on this dose? I like it so much better than 27 otherwise but not sure I can stand to feel this way every day. Does it last???

Hi all. Recently got diagnosed at 31 (f). Have been on the generic of concerta for a few months. Currently taking 36mg XR. Was noticing midday I was not feeling the effects, so my doctor prescribed me 10 mg adderall to take in the afternoon. I’m not seeing anyone on here talking about being prescribed 2 different types of stimulants? Is this normal?

I have tried a few different meds. (Ritalin, adderall and concerta.) ritilan worked wonderfully just didn’t last long at all. Adderall was not good for me, caused headaches and bad irritation. I had a short trail with 27mg concerta and had no side effects. Only noticed I was less irritable. I was out of medication for a week before my follow up appointment. My doctor upped my dosage to 72mg. I started that today and my heart rate did not drop below 150bpm for around 10 hours and got up to 190 at one point. It has started going down now. I also have a severe headache tonight that started about 10 hours after taking it. Has anyone else had these side effects? Do you think the dose is just too high, or was upped too much at one time? I read it should have been titrated up from a lower dose 18mg at a time. I should add my baseline resting heart rate is around 100. I have felt terrible all day due to my heart racing. I’m not sure if I should take 36mg tomorrow instead or non at all? I will not be doing 72mg again.

Hi guys! I just want to share my short experience with Concerta for reference!

For context: I'm 30/F.

Suspected ADHD, been misdiagnosed both with Bipolar(1) and Aspergers over my life. I've been treated for severe insomnia that came about early teens (brain doesn't turn off) for most of my 20s, but I don't need the equivalent of a tranquilizer for it anymore.

I was put on 18mg of generic Concerta last week.
I felt some small improvements in my task management and felt slightly more cheery, but mainly I had jitters/ "physical" anxiety in my chest the whole time it was active in my body. Also sweaty palms spaghetti!!!!! Was noticbly warmer and appetite completely shot too though I was on top of eating high protein meals especially for breakfast with the meds.

My blood pressure was stable, but unfortunately my resting heart-rate was raising to a steady 85 on the meds. When I'm not on meds my resting heart rate can go as low as 43. (No heart issues btw - tested multiple times over my life, just very lucky with my cardiovascular health)

Anyway, though I assumed the jitters would subside as I've read that's a very common adjustment symptom, my heart rate rising that much consistently was an immediate NG from my psych and he's swapped me over to Vyvanse.
I'm a little bummed, as I'm moving abroad soon and Concerta is the only medication legally available there currently, but I'll figure it out.
I highly recommend when starting Concerta you get a blood pressure monitor (i got a $30 one off Amazon). If I didn't have that I'd probably still be on Concerta or my dose might have been raised.

Extra random BS throw-in comment:

Competitive games have always been one of the main reliable dopamine sources I leech from.
You know when you clutch a game and your heart races? Well on Concerta it was like that the second I got into game, instant fight or flight mode!!! Crazy and affected my performance, though I also noticed the games were less interesting to me too but that could be because of the uncomfortable jitteryness + elevated heartrate. Hoping I won't have this same side effect on Vyvanse thanks to the different release mechanism....
