just want to elaborate more... i have been struggling with stomach problems for years now. Tried so many GI doctors. All they do is perform scan, endoscopy etc., and prescribe the same medicine which i have been taking for years. Something in my stomach just causes constipation, belching, even if i drink a half a glass of beer i fall sick the next day. No one seems to find out the root cause.
I have a of hopes on this fast. I am on day2, slightly starting to feel hungry and a little headache but nothing major.
