What's the longest you've been without sleep?

When I do a 24 hour bike race, I usually wind up awake for around 40 hours between "get up time" the 24 hour race itself, then breaking down camp and heading to a hotel, etc.

Between 2 am and 4am of that stretch, I will often have visual hallucinations. Nothing like seeing things when you're riding a bike in the dark - LOL! Definitely makes things interesting.

"I haven't slept in 20 days.
I should look an awful sight.
But it doesn't bother me a bit,
'Cause I always sleep at night."

While I was still on the tools the occasional emergency repair would pop up that would require working through the evening and into the next working day.
I would just stay awake until the next sleep cycle and try to go to bed at the regular time.
