I have, yes, but not often. I take diazepam sometimes or just some melatonin. Melatonin is stronger than Ambien for me, I'll eat like 1mg and completely crash. It can however cause difficulty falling asleep at first.

Zzzquil I don't know if I'd want to try, syrups like that disagree with my stomach a lot. But if there's one with just DPH maybe it wouldn't be so bad.
