I’ve fasted quite a bit, and the first two to five days of any fast your body never wants to go to sleep when you want it to sleep. It’s been my experience that after seven to ten days fasted, my sleep cycle is basically ‘ideal’ — for me that’s getting tired between 2200 and 0100, and waking up naturally between 0600 and 0830.
