For me, a clean diet and the addition of HCL, enzymes, and bile acids at every meal was required to feel any degree of good and keep digestion going. I really think going after parasites in a strong manner is what is best for me personally. I have never done this in the 5-7 years since I started going downhill, or parasite cleansed ever for that matter, so here goes well... I hope.
I have read the belief that as long as the body is strong and bile production is sufficient ect.. that slowly parasites will be reduced or eliminated naturally.
