Hey,
I have been experimenting with dry fasting without water and food in the past weeks.
It seems to be amazing for both cleaning the body with Autophagy and also to cure psychological ailments.
Today I am doing another dry fast of at least 24 hours. Tomorrow the day will feel amazing.
As a recommendation I read 20 Questions & Answers About Dry Fasting by Sergey Filonov.
There is not much content available about it in the Western world. Most of the research seems to be from Russia.
