> I went 2 weeks without food. Just water with a little bit of salt. No food. I took antibiotics the first week but not the second. I felt very sick. The fast ended. I had a vegetarian meal. I fell asleep. I woke up the next day and had a large vegetarian meal. That night I felt funny. The feeling was similar to that moment, if you have a flu, when the fever breaks. With a flu, you get sicker and sicker till a moment the fever breaks and then you know that your immune system has kicked in. That was exactly the feeling that I had then. After 20 years, my immune system had finally kicked in.

On a related note, you might want to take a look at fast-mimicking diets (FMD), and one of his more credible proponents, Dr. Valter Longo. I've met him personally, and read some of the papers and material that he has published. It strongly relates with the last part of your article, in which you are trying to guess why fasting cured you.

Happy to hear it ended well for you. I can't imagine how life has been for those twenty years, on and off antibiotics, never able to understand what the real problem was.
