Well here is some info that will hopefully reduce your stress; the cleanses are not going to heal your infestation and don’t do too much in reducing the candida or parasites numbers. You are still going to have candida and parasites cleanse or no cleanse.
Another thing worth mentioning is that it takes a long time to get better; I tell most forum members to plan on a 6-18 month recovery time to get over candida overgrowth. You have to do the diet strictly the whole time with few slipups.
If you were to consult a good naturopathic doctor, you likely will save yourself a lot of stress, time, effort, and money and hassle. You need a holistic approach where you heal multiple organs all at once.
If you are looking at the roots of the infestation, I would look no further than antibiotics, vaccines, and heavy metals.
