Earlier quoted context omitted.
Which makes no sense to anyone who has actually managed to switch to polyphasic sleep, even for just a week or two. Pavlina is so inconsistent in his description of his polyphasic sleep experiences that the consensus on the polyphasic mailing list I ran for a while was that he was a lying about doing it at all.
Do you know someone who actually managed to live like this for extended periods? I would be interested to hear.
My personal record was 3 weeks, not including the adjustment time, but I would always get derailed by a cold. I'm really need my sleep though, I'm sure that someone with less need for sleep could do better.
I found that by perfecting the napping-on-command first (for several months, too) rather than the going without sleep, I was able to make the transitions relatively painless, until I would get sick.
