Has anyone experimented with polyphasic sleep? There was a very interesting blog on "Uberman" sleep cycle (nap every 4 hours) in the 2000s, called Puredoxyk. The author tried it due to insomnia and found it very helpful. Later she developed Everyman (short "core sleep" plus several flexible naps), which works better with work and family. I tried Uberman a few times but I seem quite nap resistant... I only ever have those catastrophic 5 hour naps, which isn't very helpful here. I'd spend the first few days of adaptation completely sleep deprived, then finally pass out and sleep through all the alarms. Steve Pavlina wrote about his experiences with Uberman. Says the most useful thing he got out of it was that now (back to normal sleep) he can instantly nap anytime he wants to. Also related and fascinating: N24, zeitgebers, etc.
