I used to take Zyprexa which caused so very much weight gain for me I made the decision to come off it. I am on mostly weight neutral medications except maybe Abilify. I've had serious gastric issues over the past year and a half and have lost a lot of weight and haven't gotten my appetite back so Abilify hasn't hit me yet. I hope your pdoc can come up with something to give you some relief from the weight gain (another med? lower dosage?).
