Depends on what shift I'm doing.
If I start at 7, then I'm up at 6:15am.
If I start at 9, then I'm up at 8:15am.
If I start at 7 the next day, then I usually aim for bed about 9:30, but typically I won't go to bed until about 10-10:35.
If I start at 9 the next day, then I usually aim for bed at 11pm, but sometimes it can stretch to midnight.
As for my days off, well, anything goes. Although I do occasionally like to get up early, for the lulz, of course.
