I worked graves for years. In the USAF I worked a weird rotation, five different shifts in five days, lots of fast rotations. Youth is the only way to handle that. Got out and a new job, worked graves four years straight. Then for 26 years I worked one month of graves in every five months. I do things a little differently than most. I do not go right to sleep as soon as I get off. I found that doing that made the last few hours of my shift unbearable. Instead I go home and do whatever needs to be done, yard work, get a haircut, work out (yuk), whatever. Then around 1100 or so I would sit down with a cold beer and read or something. By noonish I would be getting really fuzzy, so then I would hit the bed, wearing earplugs (light does not interfere with my sleeping, but noise does). With any luck at all I would sleep like a baby 'til around 8pm, then hop up, shower, shave, eat, go to work. Still be wide awake at the end of the shift and do it all over again. At the end of my last shift of the week I would just tough it out and stay up all day, then go to bed at a 'normal" time. That would instantly get me back into normal sleeping hours for my days off. Before my first shift of the week I would try to take a nap in the evening, then just tough out the first shift...
