I am a pacer. I rock sometimes, I fidget pretty much all the time. I doodle. Little movement things randomly. However, they ususally don't last so long. The only time it got out of control was when I was on Abilify. So I'm going to agree with ILADVOCATE and agree it is something to do with your medicines. Talk to your doctor because it is causing problems with your life.
Temporary movement disorders are common with (currently available) antipsychotics such including Invega. If you recieved permission from your psychiatrist to raise the dose ask them to prescribe a side effect pill that will help mitigate that those symptoms.
