I remember trying this some year ago when a lot of bloggers were trying it out and blogging about their experiences. I tried the Uberman Sleep Cycle (4x15min) but inevitably it wore me down to the point of being completely nonfunctional.

I had the same experience when I tried it about 7 or 8 years ago. When I finally decided to stop (after about 2 months on Uberman) I crashed for about 14 hours straight, and was still oversleeping/catching up every night for about a week afterwards.

I tried it for about 3 months in 2005. Things I noticed:

- I gave up caffeine the month before the trial. I had pretty significant withdrawal effects (migraines) for that month.

- I was pretty much completely non-functional for about half an hour before the scheduled nap times

- I didn't think I was impacted very much, but friends commented after that I definitely seemed less bright than normal. I hope that it was for the half an hour mentioned above, but if you want to try it you should definitely try and get some objective measurement of performance.

- I still notice effects to this day. I can nap pretty much wherever & whenever I want, and fall asleep within minutes of my head hitting the pillow. Before the trial, it used to take me hours to fall asleep.

Looks like you got one thing out of it! The ability to take naps on command!

You can practice taking naps without going to such extremes.

Thankfully the recommended uberman is 6x20-22 and dymaxion is 4x30, but there are no confirmed successful adaptations to it. Uberman is seriously difficult to adapt to, but Everyman-3 is a good compromise (several naps and a core)
