For me, it is almost 48 hours or 2 days.
I ever stayed awake for almost 48 hours
because of doing a lot of assignments at
night. I did them till the dawn, and then
went to study all day long. It was so tired!
At that time I think that if I slept, I might
be not finish my homework. So, I decided
to do them without sleeping.
