I am a son taking Concerta, and I actually think I know what's causing that. I'm 19, I've been taking Concerta since I was about 15. I never have skipped doses on weekends, and I think that's what your problem might be.
The first time I took Concerta, for about 4 days after I started taking it I had dizziness, racing heart, nervousness I couldn't stop shaking, and I was about to stop taking it, but after about 4 days those symptoms started to dissipate and it all started to stabilize, but since then I've noticed that if I stop taking it, I have to go through the same ordeal every time I start taking it again, and there's a whole different set of issues that come when you stop taking it.
When you start or stop taking this, it literally changes certain physical attributes of your brain and alters how certain parts function; if he's only taking it on weekdays that's probably causing all sorts of mayhem. Your brain isn't meant to do that.
After I've been taking it consistently for about a week though I feel great; way better than I do when I'm totally off of it.View Thread
