I tried it years ago but didn't work for long. Dr Oz says that this is better than melatonin. Lasts longer and better sleep etc.
1/2 cup hulled raw pumpkin seeds
1/2 cup milk
honey to taste (optional)
He says it is actually like a time released dose of natural melatonin so you stay asleep and are well rested. Melatonin works too fast and doesn't keep you asleep like this does. No side effects and tastes good too.
Give it a try and hope it helps! Gotta love Dr Oz!
