I've taken melatonin as well but its effectiveness is sporadic, wears off in a few hours, then I'm up again. What's effective for me is, believe it or not, Zyrtec (the allergy medication). I take it for my hay fever and it does a pretty good job of making me drowsy. Prevents looking at the 2am and 4am clocks.
