What is the longest you've ever gone without sleep, and what was the reason?

The longest I've ever gone without sleep was 35 hours and I didn't really have a reason I just wanted to see how long I could stay up.

40 hours

I woke up Saturday morning, went to an all night party and still awake till Sunday night

probably around 40....during an emergency.

I dunno. Probably a full day.

well i went to a disney all night party in may, and stayed up from 7am on thursday to 6 am on friday

so i went a day without sleeping

30hours ...driving from Georgia to panama city for spring break then partying right away when we got there.

Woke up at 7am, uni for the day.... went out at night with flatmates till 4 am ish, but I couldn't sleep when I got back so I missed sleep that night.

then I went out again the following night and I think I probably got to sleep around 3am.... so erm 44 hours I think.

probably around 32 hours, usually on New years eve

about 40 hours when i went from North England to the Alps.

32 hours all i did was play video games that was back when i 11 a long time ago! lol ill never do it again!.
