I did polyphasic sleep for three months. It is possible and it does work, but what is overlooked is how perfect your sleep schedule needs to be. When you're hitting all of your naps perfectly, you're really not ever tired and you wake up without an alarm usually.

But... if you miss one nap, life is very difficult for a good 24-48 hours. Miss another nap in that timeframe and the problem compounds. Maybe this mask will help with that, or maybe not-- I have no idea. For me the problem was being near a good sleep location every four hours. I'd try to sleep in my car, but a third of the time or so I wouldn't be able to sleep and I'd be screwed.

Anyway-- I'm glad to see people working on this. I've thought about getting back on it, but the completely hellish 5 day transition period and rigidity have held me back.

Not to mention what happens when you get a cold.

What happens?

I found that I somehow kept getting colds when I was trying to get into the Uberman schedule even though it was the middle of summer so I'd be interested to know if it's somehow related.

Well, I would get extra, extra sick, and really tired, and end up sleeping for 12+ hours. It would throw my schedule out the window.

Did a 20min nap 20mins late not count for the cycle?

I did this a long time ago, so I don't remember exactly. Typically I would get my nap in on time, but sometimes wouldn't be able to fall asleep for some reason or another.

I think going to sleep 20 minutes late wouldn't be that big of a deal... 1 hour late would probably mess things up considerably.
