I've tried almost every OTC sleep med there is out there and for my personal case of insomnia, none of them really work all that great.

I first was on Trazodone, which gave me a hang over the next day and only worked so-so to begin with.

Then Vistaril. Which gave me INSANE dreams, but did help me sleep. Unfortunately my dreams were so realisitic that I would wake up not really knowing where I was, what time it was, what day it was... wake up running, kicking, screaming... things like that.

Now I'm on Restoril. WHICH. IS. THE. STUFF. Unfortunately it's a narcotic, so I can't take it every night. But it's by far the most effective for me so far.
