What's the longest time you haven't slept?

I can understand that sometimes you have to stay awake many nights in order to get stuff done,and the longest I have every stayed awake at one time was fourty eight hours and then I sleep for twenty four hours straight without waking up,which I think it kind of scared my parents,even though I could probably have stayed awake longer if I had tried,but now that I am getting older,it is harder to stay awake for long periods of time without falling asleep,and now me and fiance usually stay up twelve hours,and then I sleep twelve hours.

I'd have to say back in the day, when I was maybe 15-17 I would sometimes stay up for like 3-4 days in a row regularly, maybe 5.. but I can't really remember. When I finally slept I think I usually was out for a good 20+ hours at a time! These days I can't really do that anymore, I get too wiped out. I think now the most I could stay up if I was really trying is 1.5-2 days. I'm still a major insomniac, but I get worn out easier now, and that's odd, because it's not like I'm that *old* LOL I'm only 25. I sometimes wonder if my years spent regularly not sleeping for days at a time might have messed me up. Who knows. LOL

It may could be my a week for me..

my longest time without sleep is 50 hrs. you broke my record 4 days that's really great. But you must take some rest. working so continues will defiantly have some negative effects on your body. Go head and sleep. Sweet Dreams

I once did the GM's diet plan for a day. At the end of the first day I slept more than 12 hours and woke up very tired the next day.

2 days, thats the longest ive gone without sleep, sleep tight, enjoy

Five days... I was doing a project for the VAN HEUSEN FASHION SHOW last year that i needed to finish the videos/graphics and other things before the said event. it took me 5 days cause of the delayed in giving me the materials. So I end up not sleeping for 5 days. Until i finished everything. I wasn't able to attend the fashion show cause i almost fainted. I just sent someone to bring the materials. But the outcome was great. I was praised for a job well done. It helped also that i have insomnia.
