about 26 hours if im not mistaken.  had an early morning and ended up in vegas for super bowl

Like 19 hours? I used to love staying up late that's all.

At least around 72 hours.  It was mostly due to health problems.  I'd go to the doctors, they'd give me a drinkable sedative for neurological procedures, I wouldn't go to sleep so they'd have to do them to me while I was awake.  I'd usually pass out in the car ride home after, and then just be too freaked out to go to sleep.  I'd also see things and hear stuff that wasn't there. or I'd close my eyes and hallucinate seeing the surgeon hovering over me, hear him talking, but I was still conscious.  I just had my brain fucked around with a lot as a kid and it resulted in many sleepless nights.  On the flip side, I'd also have spells after doctor's appointments where I'd sleep a full 24 hours.  It would freak me out.  I'd go to sleep looking at the clock at 8 PM, wake up and see it was 8:03, get up, realize I'd slept for an entire day, then go back to sleep for another eight hours.

I once went about 28ish hours without sleep. I fucked up my sleeping pattern a Sunday which is never a good idea. I woke up at around 1pm that day and couldn't sleep due to anxiety attacks that I was struggling with a lot during that time. I went in to school the next day, sleepless, before finally finishing at 4pm. I had to walk 20 minutes home and then I passed out in my full school uniform as soon as I got to my room.

Went about 43 hours without sleep from watching The Conjuring in the movies. Yup. NEVER AGAIN.

I stayed up for nearly 24 hours straight because I was playing video games.

Once went about 50 hours plus without sleep. My Gradma was sick and I was taking care of her then.

I don't sleep. Sleep is for the weak.
