It’s been awhile, but when I worked 3rd watch (law enforcement) I just k"turned the dial" of my clock. I worked from 11:00 pm - 7:30 m. When I got off work sometime I joined others at a cop bar for happy hour - but didn’t over do. Anyway, I went home, did the housework, ran errands - things that day watch people would do after work. I was in bed by 2:00 pm and got up at 9:30 pm to get ready for work. Turns out that I was the one who stayed alert and energetic throughout the entire shift, unlike those who went straight to bed, got up and did chores prior to going to work. chores before going to work and far more productive than those who went straight to bed and slept all day.
Funny story, there was a young cop who coldn’t wait for his rotation to graveyard during the summer. He planned on going to the beach all day. Well, he didn’t think about the fact that he slept on his side. Ended up sunburned down one side of his body. He had to to it again to even things out!
