I start work at 2:30 a.m. and have pretty much adjusted to it.
Take a nap when I get home and go to bed around 8.
I could start later or earlier if I want but want to get out there and get-r-done.
Going in at 11 or midnight would be brutal all though getting up any time in the middle of the night is hard.
My job is when your done you go home if watching the clock all night could be very sleepy.
