I usually go to bed sometime between 0:00 and 1:00 (read midight and 1 AM). My work schedule is generally 9-5ish, so I generally get up around 7:30 and am on the road by 8:30 or so to get to work around 9.
I know I should go to bed earlier and get a little more sleep, but as much as I like sleep, there are other things I prefer to do w/ my time than just sleep - lately catching up on the day's TdF action on the DVR, which usually has to wait until my wife goes to bed (she's not interested).
