happycheeks just want to let you know that I too sleep 10+ hours. I go to bed around 1am and get up with my daughter at 7:30am. I take her to school then go back to bed, if I am not working, from about 8:30am-2pm. And after all that sleep I am still exhausted. I am even exhausted if I don't go back to bed, so I don't think it is from sleeping too much. Some people need 8 hrs of sleep, some need 10. If you are really concerned about it, talk to your doc.
