Yes, I am following a candida diet + S. Boulardii. It absolutely helps but I am far from cured.
I am following a low sugar/carb diet but that doesn't mean carb or Sugar free. I've found buckwheat and oatbran to be great and safe. Also small amounts of fruits. But of course talk with your MD/ND for more specifics. Colostrum may help you but I wouldn't count it doing too much.
Coconut oil is great, I use it almost everyday.
The failsafe diet may help, but like I said, chemicals are not the problem, your intestinal dysbiosis is.
Your condition is more on the severe side like mine. Which means it will take time to remove the pathogenic microbes and heal your intestines.
When that is done, I can finally light a candle with getting headaches and chest pains :)
