I have done a 4 day water fast. Good for the soul and spirit.

Fun and not fun at the same damn time lol 4 days is very hard voluntarily
You just have to keep yourself busy. I also finding prolonged fasts to be very spiritually rewarding experience. I find you become a lot calmer and a lot more intuitive.
The bible does tell us to pray and fast. Thats why I do it.
