How long can you stay awake without feeling woozy?

Not even a single hour these days because my eyes are not at their best and they need atleast 8 hours of sleep every day. So, if I get to be awake for even 17 hours in a day, I will start feeling bad and headache in my head. Earlier I did spent had 60 hours without sleep!

Hi laydee. My maximum would have to be 36 hours. After that, I won't be able to do anything productive anymore. Times when I have to stay awake longer, I would take an hour of sleep and then get back to work. I hate doing this, though, as it really takes a toll on my body clock. I end up getting headaches, too. Thanks. Have a great day!

I guess it all depends. If I have something to distract me, even if it's my own thoughts, I can stay awake for two days. Although it also depends on what I'm thinking of. If it's something that needs to be done and I'm excited about it most likely I can stay up for two days. I've had to stay up on odd hours just to get back on a regular shift. That actually goes for my fiance too. We do like to get off a normal schedule, although are trying to stay on the same schedule now...

upto 20 hours i can stay without sleep . remaining 4 hours i need sleep ,otherwise i feel woozy. u are great ,u stayed for 2 days maximum. but sleep is necessary for our life. without sleep ,for more days,is not good to health and may be u can face problems in future. daily atleast sleep for 7,8 hours .

I've been awake for around 2 hours and I'm already starting to feel woozy.
