Sleep

I have a fun internal clock that has no sense of real time. It wakes me up at 6:00 am when I dont have to be up until 7:30, it tries to make me sleep in when I have to be up, and on days like today when I couldn't fall asleep till 2:00 the night before and I dont have to get up early, I wake up and can't fall back asleep. Why oh why?
