I would say maybe Trazodone. I was put on it for sleep (and was in like the 3% of whatever of the people who take it that it had the OPPOSITE effect on, so I didn't sleep at all on it)...

Seroquel maybe. It never has knocked me out on its own, but mixed with Klonopin it does.

Ambien isn't worth it, IMO (and it's a controlled substance, so your doc wouldn't prescribe it anyway)...but I did a lot of sleep eating on it, and it pooped out really quickly for me as well (the sleep it gave me was great for the first month and a half, then it dwindled, and by the middle of month two, it didn't put me to sleep or keep me asleep anymore).

But now I sleep at least 7 hours every single night, and that's with Seroquel and Klonopin. My pdoc is hoping that I can get that same sleep without the Klonopin since I really needed something to bring me down from full blown hypomania that was pretty much on the line of mania). And let me tell you what my sleep was like before this: I would spend 1-2 hours trying to get to sleep (usually between the hours of 11 and 12). I woke up every night between 1 and 3:30, usually right around 3, and then again at 5 or 6, and that was at the very least. It was a good night if I only woke up twice. Often it would be 3-4 times. Since starting this combination, I can't remember a night that I woke up and didn't immediately go back to sleep.

Hope that helps!
