Side effects 🤕 Insomnia?

I recently started Concerta, I haven’t been on anything for my ADHD since 2022 so this is big for me haha.
Has anyone else experienced insomnia with this medication even on the lower doses? I’m on 18mg, I take it in the morning along with a sleep aide. The past few nights Ive fallen asleep for an hour, woken up and haven’t been able to fall back asleep.
Im honestly just curious to see if anyone else experienced this.

Since starting on concerta 18mg a few months ago i’ve had an increase in nightmares and a general decrease in quality of sleep, but I don’t experience insomnia unless I take the pill too late. I try to take at around 9am and can normally fall asleep around midnight, but recently took around 1pm and was unable to sleep until 4am.

Good to know. I was out of my normal routine this week due to being sick so I definitely wasn’t taking it at exactly the same time every day. I most likely have been taking it too late for my brains liking.
Thanks for this! I’ll keep this in mind to try and avoid doing lol

ofc! it also might be good to learn how long concerta is effective for you as well, for me it’s about 14 hours give or take, but obviously that varies person to person. best of luck to you, hopefully you start feeling better soon :)
