I haven't read gwern's article, but I did discover that when my sleep cycle gets weird, a few nights with a melatonin supplement seems to reset things. I discovered it by accident. Years ago I was having terrible patterns, so out of desperation I tried melatonin. I'm a little paranoid of taking anything to the point of dependency so I would only do a couple of nights in a row, then not use it until I needed it. It works quite well for me this way, but I must say that occasionally I'll have dreams that are vivid and intense (meaning it get's my adrenaline going). Not nightmares, more anxiety-like.
