Becoming very frustrated

I have done everything for these damned parasites [protozoa, fluke, others non- helminth] and nothing has any lasting effect.
When I was on the lorazepam [benzodiazapine] I had a "break" from this condition, that lasted 2 weeks. So, I know all the symptoms are related, and that the infection is extremely entrenched into the physiology of the body.

The reason I think the drug was effective at causing this break, was it overdosed some of the creatures, and it took 2 weeks for them to recoup.
This means that they have GABBA receptors. This also means they can receive feedback from our hormonal states. Ahhhh, it's only the tip of the iceburg.
These things are "plugged in"!
How do you deal with such an enemy?
Sorry, I just don't think herbs can cut it. Shroom
