I put about 15 lbs on with Lamictal, but I think it had more to do with the mixed episode I was going through at the time I started it. Then I gained another 25 practically overnight with Zyprexa. Now I've lost all of it and then some, and am at a lower weight than I've been in almost 3 years. I'm on Geodon now and I haven't seen any change in weight---maybe up a couple of pounds, but nothing I'm alarmed about as my appetite still isn't very big.

Some people lose weight on Lamictal, but I wouldn't count on it.
