Hey Pandas,what's The Longest You've Gone Without Sleep (And Why)?

Slept 2 hours overall in a day because my English project was due the next day

I think it was about 24-30 hours. I was traveling.

30ish hours, due to travel. Munich to London, 7 hour layover, London to Chicago, about an hour waiting for bags, Chicago to UW Whitewater, and then a drive home that I fell asleep during.
