During the late 60s would often go the whole weekend including Friday without sleep. Used to take speed to keep going. Then you crash and sleep for a day.

31-32 hours is about the most I could ever do without collapsing.

Now I have done this 2 times consecutively, so I've gone about 60 hours once with only a single hour of sleep.

Not more than one night and I haven't done that in about 10 years. I used to party all night then go to work when I was 20 or so, could never do that now.

a few days

36 hours max

Close to 48 hours

30 or 40 days several times when coming off of painkillers, I may have nodded off for 5 or 10 min every few days or so over that time but that's nowhere near enough sleep to function normally, I felt like a freaking zombie....I still don't really sleep much, the most I usually get is maybe 6 hours and most nights only about 3 to 4 hours.

I went without sleep for 3-4 days and when I looked
myself in the mirror. I looked like terminator, it's crazy.

Badly wounded, terminator.

Like half my face was cut wide open or something. I will not
do that again ever, haven't recovered yet after this trip.

Now I have insomnia. I can't really sleep at night.

When I was younger I did about 4 days, near the end it was like tripping. No drugs were involved, just didn't have a place I felt comfortable sleeping at. I got all goofy and started seeing trails. I don't know how people can go longer than that.

over 48h without sleep, no redbull, cofeine or sth.. :)
(24h roadtrip to amsterdam, and partying for next over 24h xd)

About 40 hours

try cellucor D4

my cousin and I had a challange when we were younger.. 3-4 nights of missed sleep. it was really hard, we both gave in and said fuck this..

nowdays I cannot miss a night of sleep.. if I do the next day ill just pass out, but I only need like 3hrs and i am good

40 - 48 hrs.. If I can remember correctly.

about 2 days then I had to fly not fun.

I never sleep because when I lay down and close my eyes, I spend all night wide awake in the dream world.

Must be the cocaine.:2 cents:

Probably 48 hours, maximum. Anything over and you'll be hallucinating.

about 44 hours while working on a nuclear warhead.

Yeah probably in the 36 hour range or so...

The guy who posted above that he stayed up for 60 hours is an ANIMAL haha!!!

Don't remember...
