What is the longest you've gone without sleep?

[David]

38ish hours like 5 years ago. probably would have gone longer but everyone else caved and fell asleep so i went to bed.
haven't done anything stupidly long since then, if it ever gets to like 4am and i'm still awake i'll go to bed.

78 hours when my insomnia was at its worst. Luckily it's not so bad now.

Probably like 24 hours maximum.
