for some reason I read this as "internet fasting" and thought to myself "that's a great idea", to have some downtime from the internet and electronics lol.
anyway, good luck on your program. It does sound pretty difficult to go that long without eating. Are you still doing liquids? or absolutely nothing?
once you get used to it, it's very easy...and you become more productive since you shift your focus from food every couple of hours. I drink water and black coffee during the fasting window.
