My mother recently had a neck surgery, and I work over nights. I got off work at 7:30am and went straight to the city to be with her. Went almost 48 hours without sleeping. Trust me, I don't want to ever do it again.
144 hours(6 days). On a camping trip when young a group of us decided to see who could hold out the longest... Oof, dumb idea... , I came in second , slept 36 hours straight after . And will NEVER willingly do that that again!
It was 3-4 days. Watching my bed ridden and dying grandmother. We took shifts, but I couldn't sleep at all. I was 12. All my aunts and cousin were there. Nobody could sleep. She died the night I finally managed to get some sleep.
