a little over 27 hours

.

i've honestly never gone over 24 hours, dunno how people do it
i pass out after being up for 18~ish

i once stayed up for 72 hours and i started tripping and hallucinating for a few hours then i just dropped asleep, it was for sure one of the most frightening experiences of my life

after 24 hours I start puking everything I eat but I used to stay up 2 days straight every couple of days. You should ask me how long I have gone without showering, that's really impressive.

62 hours. I have awful insomnia and struggle to sleep for more than 4 hours most nights anyway though. Wouldn't recommend. It feels like you're dying and your brain has 500 ping when you don't sleep for that long.

83h

36h, after that I get spooked like I'm gonna stay up forever and I force myself to sleep even though I'm almost never tired at that point

I once went for 30h and then immediately passed out in my chair, shit's not fun.

After surgery on my arm at the age of 16, I went for about two months without falling unconscious. It was quite strange; I laid in bed and rested, but I was awake the entire time. I wasn't fully awake, but I didn't fall asleep. When the time came to get out of bed, I was rested and ready.

It's literally impossible for me to stay up any more than 20 hours after I wake up, cause at around 18 hours or so every night, is when my eyes will get super bloodshot and it looks like I'm high af. It's pretty fun staying up late sometimes though, can't lie. I'll never do an all-nighter though, it's impossible for me to

I remember not sleeping for two days in a row and i dont recall much from that day, i was super tranquil but overall my memories about it are blurry

one time i watched Scorcese's Casino with my friend after an all-nighter, that was quite enduring but i still finished the movie and somehow even enjoyed it

If I can count not sleeping for more than one hour a night, somewhere around 4 days. I had about a year where I just could not sleep for more than an hour or two at a time. Completely fucked me up. I kinda stopped being a person after a while, sorta just botting through life. Lost a lot of friends, failed a lot of classes, and don't really remember anything about that time other than how shit it was. Tried Nyquil, Melatonin, drinking, but I just spent most of my nights with my eyes closed, waiting.

Kinda gradually started being able to sleep again over the course of a few weeks. Very suspicious that my recovery happened somewhere around the time I started smoking weed, but I don't wanna say that was it for sure. One of the biggest regrets of my life is not trying to see a doctor back then; that shit can fuck you up for life. Totally changed the course of mine.

~50 some hours, not by choice.
Happened about 7-8 years ago
Volunteered to work 16 hours starting from 3rd shift at the factory, baby momma' cold dropped the kiddo on me, and none of my usual sitters were around to drop everything and come over (at 7pm) unplanned - so I just stayed up to the next work night and did another 12 hours. Then when I got home at 11 am I was stricken with the most profound insomnia. My body was completely and utterly exhausted, but I had a pronounced anxious/tense feeling, and no matter what I did I couldn't sleep, so I just stayed up through to the next 12 hour shift. When I finally got home, I had already put all my ducks in a row so I could sleep the whole day, and utilized a bottle of wine to make absolutely sure I'd fall asleep, and did so around 1 pm once everything was in place. It paid well though.

personally almost 40 hours dealing with flights/delays etc. rough trip.

Also ppaleun how tf did you almost go for a week, i thought you could only be up for around 5 days max, you're insane dude

2 semesters ago, i stayed up for ~100 hours straight to do homework, go to class, rinse & repeat (with a few 5-10 minute stretch- & snack- breaks here and there to stay awake). each assignment i had to do was important enough where if i skipped them and got 0's, my best-case scenario was <= an 80% in the classes if i got perfect grades on the rest of my assignments. i didn't procrastinate; my database class moved up the due date on a project from a week to 2 days due to my professor's motivations to familiarize us with more material before our final project. this left me just over a day for each of my 3 assignments due for the week.

come the end of the stretch while i attended my last class of the week, i had radiating pain in my chest, a loss of breath & itchy sensations in my left armpit. i literally stumbled my way back home after the class ended & worked about 8 more hours on my last assignment. when i could finally lie down after turning in the final assignment online, i couldn't immediately fall asleep due to intense visual & auditory hallucinations that lasted about an hour.

ever since then, i've had pulsatile tinnitus in my right ear which is amplified by stress &/or further sleep deprivation.
i've posted about this before, but the consequences of a stretch from 2 semesters ago were frustratingly debilitating last semester (the pulsatile tinnitus completely destroys my sleep quality &, when audible, my ability to focus) & i just wanted to rant.

i had an MRI of my head & neck over the summer which came up inconclusive (good in the sense of no observable damage, but bad in the sense of lacking a diagnosis). none of the doctors i've been to (including an ENT) have offered any useful advice other than to take OTC sleep medication without regard to developing tolerance just in order to be able to sleep. i refuse to do this on the sole basis of certain sleep medication (namely diphenhydramine which has been the most effective in improving my sleep quality) being potentially neurotoxic with long-term usage. even if my condition is currently physically inhibitive, it seems to have had minimal effect on my reasoning faculties. i can't chance my long-term prospects due to symptoms which may only be in the short-term. my condition has admittedly improved over the summer by taking it as easy as possible (i.e. the "whooshing" sounds happen less frequently & aren't as loud unless i bend over or otherwise contort my body). unfortunately, i also have radiating nerve pain of various intensities in my digits which seems to have gotten worse over time (namely in the joints of my toes with very slight discomfort in my secondary & tertiary knuckles of my fingers) & correspondingly confound my sleep problems.

regardless, i sincerely regret not swallowing my pride & asking for an extension. over a year of this shit is awful & i wouldn't wish this on my worst enemy.

jesus christ dude that's insane, how many classes were you taking that semester? and what are auditory hallucinations?

only 5 classes for a total of 18 credit hours. auditory hallucinations are those related to hearing (i.e. hearing sounds that don't actually exist). namely sounded like men of varying distances whispering or suddenly yelling syllables (swore i heard my name a few times & jolted out of bed), the building creaking (the building i live in is stable & rarely, if ever, creaks), and a few times before i completely fell asleep i would be jolted awake by a really loud beep (to reiterate, none of these sounds could've been real).

the main visual hallucinations were: shadow-men & shadow-animals (such as snarling dogs near my doorway and rats in the crevices of my bed sheets), LED's on the electronics around my room (i.e. my desktop's monitors, my laptop, and my smoke detector) being extremely bright for a split second, and the walls "bleeding" colorfully.

it is worth noting that, while i noticed some "color bleeding" visual distortions as i was working during the end of the stretch, it wasn't until i lied down that both the auditory & visual hallucinations really came into full effect.

overall, it felt what i imagine would be a really bad LSD trip.

I thought my 43 hours experience was bad and then I read this thread

Did u get a good grade?

26 hours or something, i dont like being up for really long because i begin to talk alot and say whatever comes to my mind regardless of how dumb it is

i did well on those assignments & was fortunate enough to get all A's that semester (admittedly low A's, but it doesn't matter as very few classes at my school differentiate between A-'s and A's). worth noting that i failed a test in my easiest class of the semester during that stretch (principles of programming -- i was too focused on my homework to study for it & too tired to focus during the test itself) and had to make sure i got 100% on all my homework & >= 90% on my tests from then on to pull the grade from a D to a low A. looking back, even though i consoled myself that this was a strategic compromise, knowing i bombed a test made that week much more stressful than it probably should've been. if i prioritized the test, it would've potentially dampened the symptoms from the all-nighters. hindsight is 20/20.

i've always hated (most) tests & i could go on a whole other rant on them. from what i've seen, (proper) homework & projects are much more useful in long-term understanding & mastery. i know too many people in my cohort that barely grasp complex parts of our current material as they fuck around on homework, but they do great on most of the tests because they have strong short-term memories (much stronger than mine, at least) & the tests tend to regurgitate an inorganically large portion of the material rather than promote the reconstruction of theorems & algorithms through fundamentals. much of the problem has to do with bureaucratic, departmental pressures on professors to produce good grades while assuring said higher-ups of their students' mastery of material that the professors are usually constantly behind on. easiest way to do that is to essentially make obscenely long tests that use "test-bank level" question/answers.

one week

>i thought my 40 hours was pretty long
then i read through this thread, jesus christ wtf

80~ish hours,
had hallucinations and real bad paranoia, I thought my friends were talking smack about me all evening, even though they've been talking about plain casual stuff

a little under 72 hours i think, a few summers back i pretty much pulled all nighters as much as i could for really no reason at all other than that im addicted to videogames... i have no social life

around 34 hours i wanted to fix my sleep schedule and if i slept i wouldnt make it to scrim, and then i puked and slept missed scriim

43 and i never want to do it again

51 hours due to flight troubles
Plane could not go where he was supposed to, landed down far from home, missed the 1st train, took the second one, got home then my TF2 team leader back there call me and ask me to merc for war and offi, still did decent, after that could not sleep, so i went to bars then come back later, finally suceed to sleep
