Polyphasic sleep - sleeping less and better? - Not really

I finished my polyphasic sleep experiment. I just couldn't catch up enough sleep in proper period. Kid wakes me up twice per night - so it's hard to maintain core 4.5 hour sleep block. It was very hard to get up and you can imagine the rest of the story. I guess that my overall "time and productivity" ratio decreased. I lost my dream memory too- it's an early sign of sleep deprivation for me.

So I decided to break it and gain more rest from my classic 6 hours sleep schedule, plus occasional power nap at late afternoon. After about two weeks of adaptation I feel like I had never changed my sleep habits. I feel more rested now, so probably it was good move.

The most important lesson I learned during that experiment:
Shortened sleep time needs maxed out rest results during sleep. Taking naps with regular schedule and doing it in comfortable way (comfy place, silence and darkness) is a must.

Maybe next time when I could organize my bed time without interruptions, I will try polyphasic schedule again. Besides, I'm still working on improving my sleep habits.
