You have tried everything and it did not work to get rid of Candida.
Have you tried eating Kimchi, Sauerkraut, yogurt, Kombucha, Kefir with meals on regular basis? If not, I would try that first.
I personally do not believe in fasting and drinking your own urine because I feel during a Water Fast a lot more toxins come out in your urine, why would you put that back in your body?
Other way to populate your colon with good bacteria is to take enemas with probiotics and warm water. Also you can add a very small amount of garlic juice in warm water and do the enemas daily for a week. Be careful though, enemas can be addictive.
