on tv last night, there was a small segment about the use of melotonin to help kids with some problems, get a better night sleep - which in the end helped with day time behaviours.
years ago, when watso did some shift work, watso sparingly used a tablet called restavit - which was available over the counter.
watso had a quick look on the net, and it seems that melotonin is a natural hormone (or whatever), produced by the body.
it looks like melotonin is available over the counter... mmmm well, maybe not because from the abc website
