5 days. In high school, a buddy and I decided to see how long we could go without sleep. On the morning of the 5th day, his mom comes into his room, exclaims, "You are still awake...?!?" and then tells us that breakfast is ready. She was a true German Hausfrau... and dressed traditionally. We burst out laughing in her face... because by Day 5...? Everything is funny.
The parents shut down our experiment for that night-- and I awoke 24 hours later, on Day 7... completely sleeping through Day 6.
A week - when my coffin's lid was jammed shut and I couldn't get back in
That is a hard one, although I do remember one time about 60 hours. I was in hs. But when my mom was sick and dying, it is hard to say how long I went with-out sleep. I was in a daze and fog for months.
counting a few snoozes per day, about a week...
