Day 7: Broke the full fast after 2 days. Been on semi-fast for a week now & will continue the semi-fast for next 23 days. Lost lot of weight (12-15 pounds), feeling a bit weak & dizzy, had black stool ... seems like lot of bad gut bacteria/fungi were flushed out. Sigh. Now on coconut water, very dilute moong soup with culinary herbs & of course morning urine. Will slowly add well fermented goat buttermilk to re-establish good gut ecosystem. Yesterday, I took cabbage juice & added apple cider vinegar which was probably in excess. I reacted to it badly. Had my typical leaky gut symptoms - bodyache, headache & feverish. Maybe I'm allergic to cider vinegar (?) especially when in excess. Thanks to all of you on this thread for providing invaluable tips.
