I just found a few more encyclopedias in the Library. I decided to check out the general psychology books and found a plethora of sleep information.

Record
It seems that Randy Gardner [wikipedia entry] is the leading Guinness record holder since 1965 for staying awake the longest. He managed to stay awake for 264 hours (11 days) and at the end showed no signs of mental or physical deficit. I stumbled over this in Magill’s Encyclopedia of Social Science Psychology vol. 4. After the 11 days, he supposedly slept only 14 hours 40 minutes, then the next day 10 hours 30 minutes, 9 hours for the third day and then resumed the 7 hours a day schedule he had before the experiment.
Scientific American speaks of this and claims that Randy Gardner was “basically cognitively dysfunctional at the end of his ordeal.”

I’m not sure how accurately I can trust this one experiment. In 1965, communcations and witness were both much easier to trick. I’d like to see the records for the past couple of years. It’s possible that this was a hoax. If it is, the record may hold because it may not be merely unsurpassable but actually unattainable. I’m not sure what, if any, checks the Guinness Book has against older records. If anyone has any info, comment and post a link to a resource.

Diet
Something else that was interesting is animals that don’t sleep in long blocks tend to eat smaller portions more sporatically than large predatory animals, which usually eat few large meals.
I’ve been eating snacks rather than meals for quite a long time and I find it works best for a napping sleep schedule. I haven’t been consuming caffiene or sugary foods either, which I think eases up on unnecessary drowsiness.
