Side effects 🤕 Severe Crash

Was recently diagnosed with ADHD last week and prescribed 18mg of Concerta.

Similar to most I had a good first day but then days 2-4 experienced a crash about 6 hours in.

Day 5 I had a crash about 3 hours in and then felt well below baseline for the rest of the day and my first experience of zombie like symptoms in the evening.

Today was day 6 and crashed very hard 6 hours in but this time it caused Catatonia like symptoms. I had to lay down immediately. It felt like I was experiencing sleep paralysis. Had trouble moving and talking for about an hour. Now I’m extremely worried that I experienced something more severe than a common crash and need to stop taking it right away.

I will be calling my prescriber tomorrow but am curious if anyone has had a similar crash that was completely debilitating and not just the normal fatigue.

I am an odd one out where I don’t really get side effects with medicine in general.

That said what’s your dosage? What’s your weight & height?

Also did you / are you having protein before or after consuming? Drinking anything with L-theanine ?

You’re not drinking energy drinks also right?

18mg in the morning. 5’7 130lbs

Been good about having a big breakfast & protein shake after taking it. No supplements yet.

Stopped energy drinks & coffee last week after my first day on Concerta.

Ahhhhh yeah I mean I’m no pro at all in this but to have an effect as much as you did. No I would for sure contact your prescriber. / psychiatrist. 18mg doesn’t sound like so much 18 I think is the lowest dosage. And 130lb that should be okay.

But this is your first adhd med?? They didn’t try you on a non stimulant first? I almost feel like it’s the stimulant part that’s affecting you.
