OK, should I take melatonin or not?

I would like to say that I have a definitive answer for that question, but as it turns out, the answer is: “It depends”. There is a plethora of research out there on the effects of melatonin, and most studies show it to have benefits even beyond helping you sleep. However, I will keep my comments related to sleep, as this is the reason most of you are taking (or have taken) melatonin.
