I got a big bottles of melantonin and DHEA at supermarkets last trip to USA, dirt cheap. If you know anyone traveling there, strong vitamins are one of the most worthwhile shopping items!

I very occasionally take 3mg Mel and it very mildly makes me sleep, like having a beer. Maybe I should try two tabs since I see a lot of people say they take 6 mg. I seem to feel sleepy longer in the day afterwards though, right into the afternoon. It's not a deprived of sleep feeling, just a slight blur.

@sushi Do you have DHEA as well?
