What was the longest time you went without sleep?

Well, I had a baby 5 months ago and up until last month she was extremely colicky. So, I have stayed up about 2 days with no sleep with her, It is hard, especially when you want to go to sleep, but cant

almost 2 days..I was waiting for something and all I did was laying on my bed. I didn't even eat..

Two full days being wide awake and active. It got to the point in the end I was starting to nod off no matter what I did. We were on a drive through 2 states and only had two drivers/occupants in the car so neither of us dared to sleep in case the other fell asleep at the wheel. And we weren't able to sleep at a rest stop when we stopped and tried.
