I was pretty small, upstairs, when I was in my 20s and much of my 30s. Weight gain did give me a little more there, but what really seemed to do the trick was Risperdal and Invega. I can't say I particularly liked those two medications, otherwise. They gave me plenty of less desirable side effects. I suppose if I was a male or child, this sole "bonus" would not have been nearly as appreciated. Perhaps not all women would experience this. Maybe only those who have some hyperprolactinemia side effect?
