Jet Lag

Every night since my return, I've woken at some point and been unable to sleep for approximately one hour. Initially, it was 3 AM, then 4, then 5, until today, when I woke at 5:55 AM and was unable to sleep until now. The light is coming in the window and I doubt I'll be able to fall back asleep at all this morning. It's the beginning of the semester, the time when I can sleep in and relax and socialize. But no, my body disagrees...hopefully it'll fall into line soon. This Sucks.
