The alarm goes off at 6, I get up pretty soon thereafter.

I have to be at work at 9:30 (and work until 6). I arranged my schedule this way so I can exercise in the morning (because I was going to, one way or another, and was tired of being "late" all the time for work).

If I'm out the door by 7, I can be at the gym by 7:30-7:45 or so, work out for a bit (a little over an hour this morning), plus time to change before, and shower and change after, and I can usually still get into work a little earlier than my 9:30 report time, even with stopping off to get a bagel and/or coffee. I can snarf the bagel at my desk while checking email/voicemail, so no loss of time there.

Bedtime is usually 11 or later, though I try to aim for 10, 10:30. And yes, I do sleep. ;) If I didn't get enough sleep (like Tuesday night), I skip the workout, sleep in until 7 or so, then push the workout off to the next day.
