Keep an eye out for rising anxiety and general crankiness/assholery. Similar to how steroids effect some people’s moods reeeeally badly, melatonin has a similar effect on a minority of people. My son looooooves it, but I become the BitchQueen on it. Luckily it also f*cks up what little sleep I do get, so it’s not a hard decision to not take it. No benefit + f*cked Up Side Effects = Easy Choice.I've just started taking Melatonin too, suggested by my T. It is really good. Only problem is it is not sold commercially here, so have to order it in internationally.
