There was an article in NYTimes a little while ago that suggested that getting six hours of sleep a night for two weeks was equivalent to being awake for 24 hours: http://www.nytimes.com/2011/04/17/magazine/mag-17Sleep-t.html http://www.nytimes.com/2011/04/17/magazine/mag-17Sleep-t.htm... All told, by the end of two weeks, the six-hour sleepers were as impaired as those who, in another Dinges study, had been sleep-deprived for 24 hours straight — the cognitive equivalent of being legally drunk. My personal experience certainly tells me that a solid eight hours a night makes me far more productive than consistently getting six.
