I took Ambien for about 2 1/2 months before stopping. It lost its effectiveness, AND I was sleep walking and sleep eating which was scary.

I tried trazodone which had the opposite effect on me and had me *wired* as did Lunesta.

Have you thought about Seroquel? Lots of people use that for sleep. It works pretty well for me, though in periods of high anxiety, I take klonopin to sleep and it works quite well with no ill effects as far as I or my pdoc can see.
