I have gained 15 lbs on the Zyprexa but since I was 'anorexic' the 15 lbs helped raise me up into a more normal weight range. It totally gave me the munchies for a while. Is it the eating or something else that creates the weight gain do you think? It seems to work for me and I am afraid to not take it at this point. I've been on it for about a month and a half.
