Winter Break Hibernate.

Winter break was great!  But one of the downfalls was that I slept way to much! I stayed up until about 4 every morning and did not wake up until 11 or 12.  It was fine and all when it was break but now this week has just been terrible.  I go to bed at ten, but I wake up at 4 and feel awake. but around last hour i just crash, then come home and fall asleep.  But then I cant sleep at night! hopefully this gets sorted out soon!
