How long have you lasted without sleep?

Last year I have to remain wide awake continuously for two days and as many nights.It happened when my brother-in-law expired suddenly.It all happened so suddenly that we felt shocked and stunned.May be the shock served as a stimulant and I had no difficulty keeping awake for so long.Earlier I had once spent one sleepless night while travelling by a bus through a dense jungle.The next day was a busy day and I could not go to bed before 11 pm.Now I can remain awake at least for two days and two nights.

if i dont get sleep it messes me up big time and i usualy get very sick.. with my bi polar and all.. i need plenty of rest and not be stressed and i did go one time a week i could not sleep and it was terrible.. i got very sick.. and ended up having to change my medication.. but now i sleep pretty good.. and dont ever want to experience no sleep again.. as it is harmful to anyone not just me.. sleep is needed for the body to rest.. i at least need 6 hours for me., but try to get 8

I was about 48 hours without sleep and it was when I was young many tears ago.As for today my wife said that I can sleep without end.

The longest that I've been able to last was not sleeping that night. After not sleeping for an entire night, the following night, I do feel as though I need some rest. That's really the longest that I've lasted. It's not something that I do very often, or try to do often.

There was one time where I went about a week with maybe three hours of sleep at the very most. Needless to say, never again. I will never for the rest of my life do that ever again. Granted, it was for a project that I needed to get done, but when it was done, I crashed like a baby and I was done for the rest of the day, no way, no how. I think that any more than a day and you're really going to run into some minor issues, with the minor issues being major. And a day may be rather generous. Then again, I'm on a strict sleep schedule, when its time for me to go to sleep, then I'm going to sleep, no matter how everything really falls into place or doesn't fall into place. So essentially sixteen hours. That is how I roll.

Me too. I just can hold for a day without sleep and it takes me almost a whole day to cover it. I dislike coffee or other foods that can help me stay awake so I don't take them. A nap will not work with me as well. I don't know how people can take a nap during daylight hours..(^^)

i have on a couple occasions not slept all through the night but still went to work the next day but was exhausted that night. not sleeping is no fun!

I don't last very long, I'm afraid. Although I can stay up, my body feels miserable, tired, and worn out. I'd rather get a full 8 hours in, if I could. The only problem it isn't always possible. I usually get split sleep instead! Happy mylotting!

Me too. I normally only last 24 hours without sleep and the next thing you'll know I've slept the next 24 whole hours already. However, there was a time that I slept only for 2-3 hours for 5 nights straight. I wasn't a pretty sight the next 3 days or so. I got so sick with constipation and my allergies went on and attacked my already weak system so I'm SO sick you can't even recognize it's me. Hope people didn't experience such a thing... Happy MyLotting!

The most I've ever stay up, without sleep was 3 days. I was so tired that I felled asleep at the table eating. I had around two liters of coffee and around 5 of Coca Cola. It was the worst feeling I've ever felt. I don't recomend this tipe of life for nobody.

The longest time I was able to stay awake was two days. I was studying for my exams and didn't leave enough time for myself to prepare for one of them. I decided to stay awake at night to study. I passed the exam, but it wouldn't have made much difference if I had slept at night instead.I felt very dizzy all day and never wanted to try this again.

I do not like this experience. I must sleep everyday and sleep well . If not , I will feel tired all day and do not want to work . You are a great man ,hehehhe

Two whole days, I drank coffee like it was nobody's business,lollll. About a year ago,I was in university and I had this presentation to make, the person I was partnered with to do the presentation did absolutely nothing, so it was left up to me to get it done or else none of would've been given a mark. So for two days, no sleep but lots and lots of coffee and mind you I was a part time stuent so I was working fulltime in the day and at nights I was in school. Needless to say even though I didn't feel tired initially, by day three I crashed and burned. I never did that again, but on the plus side WE got some top marks for the work done.

I think I can skip a night and still function well without any help. Don't know if I can do it longer than that. Never tried it before, and I've never been that curious to see how much I can make it without sleep. I kind of like resting. It's good for me :).

Hi, I am too much fond of sleep. You can say sleeping is my hubby. So far I have remained awake for a night. Not more than this. And like you I too need a sleep of at least three top fours hours. And on holiday, and have nothing serious work to do I can lay like a log for as along as 10 hours. And on holiday, after lunch I need to sleep for at least an hour. I do not welcome people on such day. lol.

this is not a very healthy thing to do, so I never experimented with sleep this way. usually it would happen I only slept for like 4 hours and then I stayed awake for 8 or so more hours before sleeping again, but as I said it wasnt to 'test' how much I can stay awake without sleep, so guess that kinda doesnt count.
