I'm in a similar situation, but I haven't always been like that. I linked it to stress (in the broadest sense) - very occasionally I get a great night's sleep if I'm completely relaxed and happy. However, eliminating stress to this degree just doesn't seem feasible. My optimum amount of sleep is 8 hours, and even a half hour either way has a very noticeable (negative) effect. However, a lot of the time even sleeping exactly 8 hours doesn't work well. I really wish I could find a solution!
