According to A Brief Course in Biopsychologyby Michael J. Selby, the most time someone has willingly (meaning that mental disorders and comas don't count) deprived himself of sleep is more than 18 days . It also comments that there seem to be no physiological consequences, but it does generate poor cognitive performance while the individual is deprived of sleep.

- yea too bad the question wasnt "whats the worlds record for not sleeping?"
