I've had good results with melatonin. I just use it when I haven't slept for a few days to get me back into a sleeping pattern again. Maybe two or three nights in a row. I don't use it on a regular basis.

I wake up fine with it. I am just able to fall asleep and stay asleep. I take 6 mg. I don't have any sort of hangover effect or anything else for that matter. I don't feel drugged when I take it-just more relaxed. That's what I need it for-to calm me down to fall asleep.
