A note of concern about melatonin: I'm not saying any webbie types would be like this, but it tends to interact poorly with the endocrine systems of bipolar people. Also, regular use of melatonin can cause bloating for some people, although this tends to be more of the menstrual, not-an-issue-for-boys sort of problem.
I like Rainbow Light's Ultimate Sleep System. It is a compound with Valerian, B vitaimins, Kava Kava, passion flower, and some other stuff. They recommend 2 capsules, but I generally take 4 or don't bother.
Gaia Herbs makes a Sound Sleep compound with Valerian, GABA, Kava, California Poppy, Skullcap, Hops, and amino acids. I do the same thing with dosage on this. Can definitely impact dreams.
Of course, it is 5am in California, so ya can tell I don't exactly always get around to using either.
