What are the signs of a sleep disorder? Let me first say that I am not a lazy person....but I can sleep unlimited amount of time and still be tired.  I sleep through my alarm clock and don't get up on time to go to class (college)...it's caused problems between my husband and I because I sleep too late on the weekends, etc.  My sleeping habits, problem...whatever you call it has caused distress in my life in more ways than one.  And I have tried to fix it, and tell myself...damnit, you're getting up at __ in the morning, and I never can seem to do it...I just keep hitting the snooze, telling myself that I'll get up in 10 more min, and next thing I know it's 4 hours later.  Please help!
