ive been on geodon for a couple of months, and it has helped quite a bit with my issues. it was very sedating at first, it made me very sleepy after i had taken it, but i actually like that part because it greatly regulated my sleeping schedule and now i dont stay up till 3am and sleep well into the afternoon. i haven't experienced any weight loss/gain (at least not yet) but i have heard that it is weight neutral. and the only side effects that i have gotten from geodon was some nausea when i first started taking it, but that eventually went away. i used to be on risperdal, and prefer geodon over risperdal much more.
