your taking too much melatonin, you should only take about 3mg. taking more than 3mg can act as a stimulant, and melatonin only work for 30% of people. tomorrow don't take your medicine and drink till you fall asleep, that works good.
yupp you're taking way too much melatonin. i take about 3mg and it works perfectly. they are a lot more expensive than melatonin but give some of the sleep supps a try - AI's 3Z worked really well for me when I got the sample.

Large doses of melatonin can even be counterproductive: Lewy et al. provide support to the "idea that too much melatonin may spill over onto the wrong zone of the melatonin phase-response curve" (PRC). In one of their blind subjects, 0.5 mg of melatonin was effective while 20 mg was not.
