I take Geodon and it has the same affect of losing weight. I lost a lot of weight both times on it. I gained 60lbs with my first pregnancy, and still carried a good amount of it around when I was diagnosed two years later. After trying other meds that made me gain MORE weight, my current pdoc suggested Geodon. It really suppresses your appetite! I would eat half a sandwich and feel completely full, hardly able to finish that. After my second child, I had to get back on afer 2 weeks. I gained 45lbs with him, and lost it all within about 2 months. I had to add Lamictal because I was losing too much weight. The two together stabled me out.

So look into Geodon if you want, maybe it will work for you. A co-worker friend of mine takes Topamax, and I know that has helped her lose some weight as well. Good luck to you! I know how frustrating it is to gain weight on meds you need to survive. I was taking Seroquel before and I gained about 20lbs on that.
