You describe cycles, and dosing days, sounds like you are on someones protocol.
Since most of my protocols target an infection of worms, where there is no start and stop, I am unsure how to answer.
Sounds like you may be fighting insect infections with antiparasitics?
There are other meds, that address insect infections. You mention others, I suspect looking at the CZ history, for some of the more insect related infections.
There has been a great deal of support for using antiparasitics for Lyme and such, and as you say there is some impact on your infection, Sounds like you are missing a med or attack of the invaders chemistry that really hits them.
