What's the longest you've gone without sleeping? It's not a fun thing, but I'm 24 and have started within the last few months to develop sleeping problems. I had them a little when I was a teenager but they are worse now. In December I went about 3-5/6 days without sleeping, though not by choice. I had a weird seasonal job and it kept me really keyed up. I say 3-5/6 because three days after my last actual sleep I may have slept at one point, but I'm still not sure if I was completely asleep or not. Four days after my original sleep I definitely didn't sleep, five days later I believe finally slept a little, and six days later I definitely took a nap and slept that night (December 27th leading into December 28th). It sucked. A busy mind is terrible. In good news, I did memorize every World Series winner during this time period. What's the longest you've gone without sleeping?
