I think maybe you felt sick and restless because of med withdrawals? It's not good for your body to stop cold turkey.

What made you decide to stop your meds? I've stopped a few times and immediately got some king of manic. Definitely racing thoughts going on, and like you said, lots of anxiety. I haven't pulled that stunt in a long time though. Maybe I've learned my lesson. (I hope so, but you never know).
