I totally understand the roll back into bed at this hour thing. I worked 3rd shift for years. After doing 2 swaps in 3 days (arrived at the 1st Thurs night & got home Sat night after sleeping in the car both nights, left for 2nd at 4am Sun & got home Sun evening) & sleeping in the car for most of the (not much at all) sleep I got from Thursday to Sunday I was pretty much dead the entire rest of Sunday & half of Monday.
