From the reading I've done, people tend to go off it when external factors make it difficult to adhere to such a rigid nap schedule, e.g. every four hours on the dot, rain or shine. As with any habit that requires discipline, like being vegan or practicing the violin 6 hours a day, it's not necessarily a life-long thing.
But people commonly say things like "I did it for a year; best year of my life". Apparently you can literally go for a year getting a total of 2 hours of sleep in each 24-hour period. After a week of forcing it on yourself, if you're brave, determined, and a little lucky, a switch flips in your brain.
If that's a fact, in spite of the nay-sayers, then that's really something. I intend to find out for myself.
Yet many people are vegan for years, and practice violin for 6 hours a day for years. As far as I can tell, there is not one documented case where someone who has maintained polyphasic sleep for more than six months or so?
