I'm usually up by 4 AM, in bed and asleep by midnight at the latest. I used to be the complete opposite, and I'm not sure why this seems better now. But early early morning rocks, a very relaxing and peaceful time of day. Too bad I didn't like this schedule when I was in the Army, because that was pretty much the schedule we *had* to keep. But I hated it then, liked to sleep in until noon, party all night.
