While in the Army we worked swing shifts. 6 days on, 2 days off on days, then 6 days on and 2 days off on afternoons, then 6 days on and 3 days off on midnights......
I can't say that I had any problem with it, it was just something we had to accept.
Regular night-time sleep of 7-8 hours works best for me.
Too bad it is a luxury seldom enjoyed due to a really inconsiderate elderly mother who lives nearby and will not stop early a.m. phone calls or banging on the door “just to make sure you’re alright”,despite my 2nd/3rd work schedule.Before that it was a wife who thought sleeping from 1am to 6am should be plenty since I only worked 60-64 hours a week!
The angel is gonna have to sound the Trumpet a second time for some of us.
