Another round of anecdotal evidence: I did the everyman for about three months when my startup was doing a big pivot a few years ago. It took about two weeks of being completely blurry to transition, but once I did, it was very effective. I would wake up ~7AM and get to work, have my first ~1/2 hour nap at 11AM, next nap at 6 in the afternoon, and then a nap at midnight. I'd be totally awake and aware until ~3:30AM, and then I'd go to sleep. After the transition, once my body got settled, I'd usually be awake a few minutes before I set an alarm, and my caffeine needed to stay alert went way down. Like most of the other anecdotal evidence, I stopped for social reasons - my girlfriend wasn't a fan of me coming home from work at 6, immediately snagging a nap, and then be up rattling away until 3 in the morning every day. Also I wasn't able to fill the day - I'd be burnt out on work after 12+ hours of grinding away on some Rails code, and have to do something else, so I'd either tinker in the garage, cruise the web, or play games. Once I started up with the video games, I decided it wasn't worth it, and flipped back to a "normal" sleep cycle. It took ~2 nights to go back to a normal cycle.
