Sleep, sleep, sleep

i am exhausted.  I slept all day and all night Sunday.  After a few hours of working, i took half of the day off and slept for about 9 hours.  After being awake for only a couple of hours, I went back to bed and slept all night. Today is Tuesday and I am trying to keep from dosing off at my desk.  I wish I could find a remedy for the fatigue.
