My body doesn't know when it should be sleeping but it knows when it shouldn't be sleeping. If I get home at 4a.m. I am back up at 7. I can't sleep past about 7 no matter what time I go to sleep. A few years ago it didn't bother too much. Now I rarely will work 2 nights in a row.
I worked 14 nights in a row, I think it took 7 nights till I could sleep 8 hours in the day. A police officer told me the trick to sleeping during the day is to go to sleep before the sun comes up.It helped when i could get home before 6am. By the way strange things happen after midnight!
That's how I am. I don't like working nights anymore. It's one of my goals for next year - get my guys trained to handle our night accounts on their own.
My hat is off to the guys who do it all residential, commercial, KEC, etc... opperating on different hours depending on the day. Working nights for 2 days, followed by a bunch of day work, followed by periods of day and night work combined is a killer.
