Since 2015, I've been experimenting with polyphasic sleep-- and since early 2017, I've only been sleeping polyphasically.
My first taste of polyphasic sleep was the Uberman, in the summer of 2015. Uberman has a total of two hours of sleep every day-- one 20-minute nap every four hours. Let me tell you-- it was brutal. I started it because I wanted more free time to play games and work on projects, and that's what I got.
For the first few days, adaptation was painful, but bearable. I was able to get so much done, have fun, and the days felt endless. It was like a dream, almost. The days blended together, each one meshing and molding with the next. It was surreal, and I loved it. Sure, there were pangs of tiredness sometimes-- but they weren't anything I couldn't bear.
By week two, the pangs were bad. I started to oversleep consistently-- my 07:00 nap always became a three-hour nap-- and I was more tired at night. Instead of getting things done while the world was quiet and asleep, I was useless. I was too tired to do anything, but not tired enough to sleep. Those nights, I watched reruns of old TV. I still remember the Golden Girls and Columbo episodes, like they've been burned into my mind.
By week three, I was done. I made my decision partly because the oversleeping
(07:00 -- 10:00), but partly because of the loneliness. It felt like
I only saw people for a very small part of the day. Most of the time, everything was
quiet and I was left alone, tired and watching shitty TV.
Two years later, I decided to give polyphasic another shot. Instead of going on the extreme ``hacker'' side of the spectrum, I decided to go for a happy medium-- something between ``natural'' and ``hack.'' That was the Everyman. Sleeping for 3.5 hours, awake for 3 hours, asleep for a 30-minute nap-- then, toward the early evening, another 30-minute nap. A total of ~5 hours a day, but pretty-well spread out.
This one was actually really easy to adapt to-- it was effortless and painless, unlike the Uberman. I slipped right into it with ease. I was awake more, slept less, yet, surprisingly enough, I felt more awake and alert than I ever did on monophasic.
In fact, I loved it so much, I kept it up for seven months-- up until last month (2018-01). I started getting sloppy with the schedule, and my early-morning 30-minute nap became a three-hour core. My single-core Everyman cycle accidentally became biphasic! I suddenly realized that trying to stick to the Everyman was fighting human nature-- biphasic is the natural way to sleep, so it's kind of expected that I'd drift toward it.
I stopped fighting it.
Since early January (2018), I've been sleeping biphasically--
two core sleeps
(22:00 -- 01:30, 04:30 -- 7:00) with a single, short nap in the
(16:30 -- 16:50). A total of 6.3 hours of sleep. I'm feeling pretty good
on this cycle. Sure, I might not get as much awake-time as under the Everyman, but it's still
I'd seriously recommend biphasic (or maybe some Everyman variant) to anyone having issues with monophasic.
