Once the spirochetes are active the metal is already in your system one could make an argument that you can't make it worse..
That said skip cyst treatments and use small time session like as low as 25 second bursts. If you feel better after a few bursts then you know whats wrong.
If you are not using a lot of salt then I don't know what to say.. at least 80 human toxins cannot be removed without it and we know Spirochetes create a whole spectrum of them beyond that..
