Just finished my first day of another week long stint doing the early morning shift. Two weeks ago I worked the shift to cover someone's vacation. Now the other guy took the week off, so I'm back on it. 3am to Noon is a tough schedule to do. It's even tougher to do twice. I wouldn't mind it so much if it was what I did every day, but it's not.
However, I do mean to keep it that way.
