Hmm.... I really recommend a sleep study. There's restless leg syndrome, your constant waking could possibly be apnea (but I would expect with apnea you would be drowsy constantly). Once they plug you up with wires there's a lot of things they could find. I had sleep problems that turned out to be apnea. I was sleeping 20 hrs. a day on weekends and abusing the hell out of caffeine pills on work days. I got to the point that I seriously considered suicide. I got to the point where I stuck a loaded SKS rifle in my mouth to see if I could still reach the trigger. Now I use a CPAP machine and things aren't 100% but they are much improved.
