Uhm, yeah I'm not going to post the exact number since most people wouldn't believe it and I really don't feel like getting into an argument. But I can tell you that there are no direct long term effects of sleep deprivation and that the world record is somewhere just north of 11 days.
My personal record entailed my entire spring vacation when I was in Jr High, and it was more than half a week but less than a week. This was back when I played MMOs and I can tell you first hand how horribly unhealthy it is.
