I'm on Geodon to sleep. But it doesn't work like that for everyone my P doc says. In fact, he can't believe it's helping me, and is quite puzzled by it. It is a newer drug, and he said when they used it in the hospital...it had an opposite effect on the patients, and they were all awake using this mood stabilizer. I'm on other medications with it, so I can't tell you if that's what is making me gain weight, or if it's the lexapro, and lamictol.
