All the next generation anti-psychotics will cause weight gain in some people. Zyprexa's the worst of the lot. I've been on Geodon and Abilify, both supposedly weight neutral drugs, and I gained 89 pounds. Just changed back to Haldol.

Your pdoc is going to be the one to talk to. Don't fool around with your meds yourself. I halved my Abilify because I was so upset about my weight, and four days later, I was psychotic again.

Good luck.
