Exhaustion, Day 3

Not sure what time I went to sleep last night, but it was after midnight (my fault for staying up more than anything). I woke up several times during the night and am getting increasingly frustrated. I am holding off on taking meds to help the sleeping as long as I can (don't worry; I have a small supply on hand), but I am coming close to caving.
There is something in me really wanting to reset my body's circadian clock -- I got up at 8:00 this morning and am really wanting to get in bed right now. Problem is, it's not dark, nor is it past 6:00pm. Maybe if I'm like Paul and make my body obey me....
