"Nope ... ain't gonn'a do it anymore ... better find a comfy place to fall down on, 'cause I'm givin' ya' about a 10 minute warning."
Bingo on the sleep! You’re nailing me! Can’t make plans because like you say you get a few minutes warning then it’s down and out!
If you do manage to stay up you aren’t on all cylinders and then when you do try to sleep you can’t.
If I can make it through the summer I’ll quit, take retirement and find a day job!
