I'm currently on 300mg which I take at night. Slowly dropping down (was on 400mg before). It used to wipe me out but after a few months I felt normal sleepiness wise. I didn't put on any weight. I also got the constipation tho :-( thats getting a bit better now too though. I'm going to keep dropping the dose now too with my pdoc's supervision.

Interestingly, when I used to take 25mg as a prn it would calm me down/knowck me out ... now it does absolutely nothing.
