I am a chronic early riser, and sleeping in late is somewhere between the hours of 8-9:30am. So having a change in my schedule where I come in second shift every now and again really messes with me.
But getting to sleep in that extra bit, chill, clean the apartment, watch the Bad Brains DVD I got from the library... that was nice.
Still need 3 cups of coffee to get going though. I think this means that I'm addicted.
