Maybe a symptom of akathisia? I had to be moving around all the time when I had it. It was awful. Made me want to jump out of my skin. In my case, it was Geodon that caused it. When I got hospitalized, a doctor prescribed Cogentin and I was able to relax for the first time in weeks.

I would let your pdoc know what's going on. Maybe he/she can do something to help.
