Yeah it really does take a while. Some are in my upper back right now, causing a lot of upper back pain. The GB-4000 is working great against the Lyme. I think I want to grab the F165 for all of Newports scriipts. Gonna have to save up again. If I can save enough money I maybe able to set up a custom plasma tube system. I also think I'm gonna give Ivermectin a try and see if it helps at all.
