i take remeron everynight 30 mg. it is actually an antidepressant from a ways back. I don't see any weight gain and i am on 800 mg a day seroquel. you shouldn't get a hangover from it , it just helps you fall asleep. I have been on it so long that i don't even know if it helps me sleep anymore. But my doctor thinks its beneficial.
I wish you good luck with it.
