I am NOT a doctor, but I've heard about a new anti-psychotic called Abilify. It's supposed to be helpful both as an anti-psychotic, and as a mood stablizer and has fewer side effects. Here is some info:

It was just approved at the end of last year and there is very little info out there about it. You might want to ask your doctor about it. I heard about it originally from a NAMI parent.
