I have been doing black seed oil, ivermectin, wormwood, diatomaceous earth, cistus incanus tea, and a bit of MMS for a while... herx'd at first, but now is easy. Generally feeling "cleaner" in terms of health.
The real hard thing to confront is craving sugar... which feeds the nasties.
Perhaps add a good probiotic to your regimen. Your good bacteria may be diminished due to the IVM, etc. The good bacteria may keep yeast down. In addition to the other parasites, yeast does crave sugar.
