What is the longest period of time you have gone without sleeping?

50 hours or so...after my dog died.

About 4 days. I remember seeing my skin flaking off everywhere (it wasn't really).
It just generally sent me a bit loco.
That was with stimulants though, so I was probably a bit wound up, anyway. But compared to other stories I've heard, 4 days is amateur.

4 days, my neighbor's house burnt down right next to me. I couldn't even think about sleeping.

7 days and nights.My granny was sick and we had to nurse here round the clock.Had to go to the hospital,they shot me up w/ ativan in the afternoon,I finally went to sleep at 10pm that night.

Four days. There was a power outage a few years back and the cold kept me from falling asleep.

I couldn't sleep for a week n didn't sleep normally probly over a month when I was kicking my drug habit

I have driven for over 37 hr's and played online poker for 37 hr's went broke and drank beer after until I settled down enough to sleep. When I was a locksmith I would stay busy for 48 hr's or longer.

Up to 4 and a half days...i can tell that i was occasionally having OBEs.

5 days and nights, but I had some chemical help. We were sailing from Shelbern Nova Scotia to Toronto and the fog was so thick I couldn't see the bow of the boat from the wheel house. I sat at the radar and gave courses to whoever was on the helm.
