Talk to your doctor about the side effects and the voices. I sleep a lot as well. I sleep 12-14 hours a day and still don't feel rested. I am on Loxapine. I also take sleeping pills because without them I have the opposite effect in which I can't sleep at all or just sleep about 2 hours a day which causes psychosis in me. I am sorry that you are having problems. I hope you get better soon.
