Cool!
I tried doing this for 2 months last summer together with my brother. My parents were gone most of the time, so we had free playing grounds in our house. It was pretty fun... except for the long period of constant hallucinations in the first week which I suffered from.
After three weeks, I had to give up. My body had gotten so weak because I didn't let it recover and build with normal sleep. One day I litterally couldn't walk up straight anymore, I had constant headaches and I had bags under my eyes the size of tokio.
I stopped, but I still keep on having headaches because of it.
Coincidentally, I went to see a doctor today, that explained to me why this happened. The hormonal production in my body had been going into a slightly off cycle somewhere along the line, before I started doing the Uberman schedule. When I started doing it, it was the last straw for my body, so it just made the hormonal inbalance become so bad it started giving me headaches.
Basically, I want to advise you to be in very good condition when you're starting this. Make sure you eat enough and eat healthy while doing it.
Don't drink, don't do drugs, don't drink coffee, don't do anything that may possibly affect your sleep.
The optimum sleeping span is 21-24 minutes, after that you get into deep sleep. It's the idea that you avoid that deep sleep, but sleep so many times that it amounts to the same.
It's fun as hell though, you can do SO much work while on it, it's not funny anymore. I remember finishing a 50 hour project, in 3 days
.
Oh yeah, try and find as much info on the net as you can. It's important you know what you're doing.
