Girl do I know where you're coming from!! I get 8 to 9 hrs of sleep but still feel like taking a nap at lunch while at work (and sometimes do). I've been complaining of this for years to my dr. with no help. On the weekends there have been times that I'd sleep 9 hrs., get up for 2 hrs, sleep on the couch for 4 hrs. get up for a couple of hrs and then sleep all night long. To me this is not normal. My doc just says I don't know. Thyroid normal. Borderline anemia. Seems if they can't point to something obvious they just tell you to live with it. I'm going back to my doc AGAIN near the end of the month and I'm going to try to push the issue. Somthin' aint right! I'll let you know if he tells me anything I think could help you. Good luck.
