> I couldn't sleep much (sometimes 4 hours max)
Did you find some way to mitigate this or did you just have to live with it during the fast?
At the beginning I was really worried, but as I said I was very alert despite lack of sleep/food and I was able to work etc.
My personal take from this experiment, was that we don't need that much food/sleep to thrive, but again that was my personal experience, and I wish there was more research on that instead of the constant mainstream message (sleep 8 hours and eat 5 meals etc.)
