I've been without sleep alittle under three days before. My friends tell me I am hilarious without sleep.
Two days (48 hrs) during my examination time.
About 28 hour's. I don't know how people can go for day's.
About three days is my highest. If anything, it's mostly up to two days... I'm just up thinking about stuff, and before I know it, the sun is up and shining.
I think I did not sleep for 24 hours ( a whole day )!
I think it was about 3 days and nights once without any sleep. But that was because we were under a heavy barrage that seemed to go on forever. One of their tactics to wear us down. Then they would strike but this is common in all wars.
About 30 hours
I have insomnia and can be trying sleep for 12 hours straight and never succeed, the longest I've went without sleep was at least 3 days, I can go one day without sleep and still be hyper all day two days and I get a bit tired, 3 days and I'll get pounding in my head and be tired all day, but when night comes, I still can never sleep.
