The longest recorded time a human has ever gone without sleep is 18 days, 21 hours, and 40 minutes, which resulted in hallucinations, paranoia, etc. However most people can only last 4-6 days without stimulants, and about 7-10 days before the body will be unable to function and long term damage can be caused.

It all depends on the person, and what they do.

For example most people sleep everynight.

People who smoke Meth can go nearly a week without sleeping, maybe even longer.

I don't do any drugs and I can stay up for 2 days if I really want to.

There is no definite answer to your question. Humans can stay awake until the body can no longer handle it,

once your body can't take it any more, it will shut down in it's own way and there will be no choice but to sleep.

How long a person can stay up at a time depends on the person.

People often start feeling the effects of sleep deprivation by the 2nd and 3rd day.

By the fourth or fifth day people often suffer hallucinations.
