I was on Geodon for over 4 months in the past. It did wonders for my moods, but I had the worst side effects and had to eventually stop taking it. I too had the involuntary muscle movements, it was really bad. I had to take another med to counteract the Geodon, then I had side effects from that also. I guess I had good and bad reactions to Geodon.
You should bring up your symptoms with your pdoc right away, you have to be careful with involuntary muscle movements. For if they are not properly monitored they can become a permanent thing. I don't mean this to scare you, but just to notify you of the possibilities. So when you get a chance talk with your pdoc.
