Longest period of time without sleep?

I have absolutely no idea. Things get weird when I stay awake for too long.

Actually, I think it was only last week when I stayed up for over 30 hours. That's what I get for working nights.

Probably a little more than 24 hours. I can't hold out usually lol.

30 or so hours, due to anxiety.

Probably the first time I went to visit Norway. My flight was really early (like 4am) so I didn't bother sleeping the night before, and I had to fly to Oslo airport and then transfer again to Bergen, and by the time I arrived it was like 1pm and super bright outside. I was so excited to see everything for the first time that I just stayed up, which probably made it close to about 40 hours without sleep in total. Never again :p

I would say around 3 days or so.
