I'm not a physician but something that has worked shockingly well for me is 200mg of 5-HTP and 500mg of L-Tryptophan before bed. I used to have terrible insomnia (only sleeping for 2 hours some nights) and every time I take these two together I am out like a light within 30 minutes, and usually don't wake up at all until 4-6AM (I used to wake up fully at the end of every 90 minute sleep cycle and have to go through the whole process of falling asleep again). It gives you that warm fuzzy feeling (capillary dilation in the extremities) that you get just before you fall asleep. I've been taking it every night for five years now and I swear by it. YMMV of course. I've always been skeptical of supplements and I had taken tryptophan before to minor effect, but the two of them together are way beyond anything that could be blamed on placebo.
