How are your sinuses? Unrefreshing sleep is probably the biggest problem I have now, and I'm starting to think it's due to a chronic, low-grade sinus infection. I've been researching this and not only is trouble sleeping a symptom of chronic s.i., there are posts and blogs by people saying once they cleared it up, sleep returned to normal.
Sinuses have been partially blocked for years now. On a typical day my left one feels @ 90% capacity and the right fluctuates between 40 and 70%.
