Kava-Kava is also a good sleep-aid. GNC no longer carries it, but it is available most other places (US)

I wouldn't recommend DXM (The PM part of Tylenol PM)

But, it is available in bulk at http://AmericanchemicalSupply.com

Buy that shit by the kilo...G!

melatonin is great. like they said, don't take too much or you'll feel hungover.

and don't buy the overpriced ZMA, go with plain-jane zinc. it's cheaper and it's the active ingredient that'll make you sleep deeper. i swear by it.

See your regular doctor. Valium, xanax, ambien, etc.
