with my F-117 I only use the bulb, I've never used the footbath so I don't know about water color and things like that
As for the Herx reaction again I would say try a Mercury chelator. If you're nervous about the DMSA keep cutting it in half. Take only 20 mg or thereabouts to start out with
Or take some ALA instead. Again Start out with a very small dosage
It's been my experience that the only thing that stops the Herx from rife lyme treatments. but that's just my experience other people may have different experiences
