for how long you can stay awake?

The longest was 24 hours for me. But, the truth is, I felt like I was floating on air the entire day. I was still working back then and I was one of the supervisors in a hospital cafeteria. One time, I had to bring paperworks at home and have it ready the next day. I din't get any sleep at all, and I drowned myself with lots of coffee.:) The next thing I knew, it was already and I had to get ready for my morning shift. So, I went to work the next day and was "floating" during the 8 hour shift. Thankfully, my adrenalin kicked in when it was lunchtime. And even without any sleep, I did my job well.

When I was younger I used to work back to back shifts which meant that I could work up to 1am at night and then I had to be back on shift the next morning at 6pm, so it was hardly worth going back to bed, with the travelling time to get home and back to work again, I would drink plenty of coffee and watch the television, I didn't have many back to back shifts and in the end the company had to change them so no one got any more back to back shifts, which was a pity because the pay was very rewarding to do this kind of shifts.

well i would say i can manage without sleeping for a day.infact i have the passion for computer gaming and usually in college i keep myself awake all night playing.the next morning i do get tired.during exams also i sleep only at 1 or 2 in the morning.

hello izathewzia, Thanks for your post.I think necessity and sense of responsibility are the two determining factors apart from people suffering from depression or insomania lol,still now my highest timing has been 67 or 68 hours straight without a single second nap.Thanks again.

up to 16 hours only. I sometimes would go working straight in a double shift of 16 hours. 24 hours is way too much and I can not be awake that long.

i can stay awake 24hours for a day as long as the next day i can rest for a couple of hours, 4-5 hrs will be okay.

To stay awake for 24 hours is too long to be healthy for your body, although I guess if you are young, you may be able to do this. Probably the longest I have been awake in very recent times, would be 17 hours, when I have to get up at 4.00am to take my daughter to swimming training. I find, at my age, I ne4ed a lot of sleep.

I have stayed up for 24 hours before, but I wasn't doing well. I am sleep-deprived to begin with & have been known to fall asleep at my desk at work, fall asleep while I'm eating... I can even fall asleep standing up, if I'm propped up against a wall! And I'm bipolar, so if I stay up too long, I start to get psychotic! Yikes!

I remember when I was young, I could stay awake till six o'clock in the morning from evening. That was less than twenty-four hours, about nineteen hours, I think. Why could I stay awake that many hours? It was because I was addicted to playing majiong, a game of us Chinese, when I first learnt how to play with it. All of us four colleages were learners and we learnt together and we were all interested and addicted to it, so we used to play on weekends starting from Friday night. It was a wonderful memory though.

I once had an assignment to finish. So worked the whole night. Took a shower, went for the class next day . Had a chance to get a nap only in the evening. So it was like 32 hours or so I guess. ;)
