I haven't had a need to take Melatonin in a long time, but the last time I took a small dose (fraction of a 1mg gummy), 30 minutes later I got really cold and then could not keep my eyes open, it basically knocked me out. It was very uncomfortable (especially the feeling that I couldn't fight to stay awake) but it worked. Scared me off of the stuff for good. Thankfully, over time I've gotten to where I don't have sleep issues anymore other than those I self-inflict (late nights). I still wonder if somehow I really psyched myself into a placebo effect or something, because I rarely hear of this happening when people take it. MIT has done some studies that show smaller doses are in-fact just as (or more) effective than larger ones: http://news.mit.edu/1999/melatonin-1103 http://news.mit.edu/1999/melatonin-1103 And studies mentioned in this article seem to agree with that conclusion (0.3mg being an optimal dose)
