When left to my own devices I simply sleep when I feel tired. My normal cycle will be something like sleep for 6-12 hours and stay up anywhere from 16 to 20 hours. Sometimes I'll take a nap for an hour or two somewhere in there. As far as I can tell there's no real pattern day to day but on average I drift a couple hours or so around the clock every day. Every couple of weeks I'm back to a "normal" schedule. When I have a 9-5 job though I end up tired one day and fine the next. I end up getting up at 8 or so and going to sleep at either 11 or so because I was really tired or 3-4 am because I wasn't. f.lux actually did help a lot. I was much worse when I didn't use it (I could never get to sleep early so I was always tired.) Anyway, I'll do some research into melatonin supplements, thanks for the lead.
