How long have you gone without sleep?

Hmm, about 36 hours or so. The first time was during high school, my best friend and I stayed up all night playing Metal Gear Solid, but more recently I've stayed up all night a few times watching anime on Netflix. It really messes with my sleep schedule, so I try to not make a habit of it. ^^;

3 days but that was when i watched almost all of the english hentai on this site :3

Longest I've gone without any sleep were 56 hours, during the Diablo 2 Hype.
believe it were 7 years ago, I ended up smashing my head into the keyboard a couple of times before I decided that I should probably go to bed.

EDIT: Note that I slept for 17-18 hours after that though...

I think around 26hr playing P3P first time in my psp!

For me, it was about 3.5 days.
It was around the time thewhen I still had my dreamcast amd I was playing sonic adventure 2, grandia 2, and jet grind radio.
I wanna say I was 13 at the time. Was seeing things real later the third night, and ended up passing out for almost a full day.

Since then I can only muster up about a day before I pass out.

24 watching gundam series!

25-48
on dopaminergic

goin on day 2 gotta have my anime and hentai

I can only handle 12 to 18 hours. ; n;

I think I was about for about 33 hours on my flight home from Japan.
I woke up at 10AM the morning of our flight (on a Tuesday) and got to bed at 4:30AM (on a Wednesday). I'm 13 hours behind Japan.
We had 2 layovers and I just couldn't sleep on the planes. Being at such a high altitude seems to make my knees really sore and it bothered me too much to sleep.

Ive had over 48 hours without sleep, partly because im an insomniac, also because I was up playing games.

13-14 and it's not worth it.

My longest lasted for four days. Just couldn't find myself to stop playing some final fantasy games on my ps2. That was like a month ago. Still trying to beat my personal record though. I'm on almost on three days straight right now. Sucks to be me eh?

Not sleeping is REALLY unhealthy, but the farthest I went was 30 hours. Afterwards I felt like death. Really makes you value sleep.

24 hour I was weak and feel asleep I was going for 3 days

A day and a half. Played multiplayer PS2 games with friends overnight, and still awake at lunch the next day. Drank some coffee whenever I feel sleepy.

About 40 hours.

Once I had to finish something for college... worst two nights ever

ATM, I haven't had any sleep in 13 hours (Gaming and anime marathon). The longest time I've been without sleep was 1 1/2 days during an anime convention in West Virginia.
