Hi Clary, thanks for the vote of confidence. I started zapping with the simple home-made one about 5 years ago. I was so weak that I could hardly 'tap' the bar. Then I got the one that didn't need to be tapped and placed the bars everywhere. Under my feet, on my face, neck, spine, breasts, chest [btw, the breast pain went away, never to return], under my arms. . . you get the message. . . Just be certain to never allow the bars to dry out. Also it's very important to change the THIN, WET towels each hour. That green coloring is the copper toxin. No need to enter that into your body.
I gradually got my life back and am still improving.
YES, I had silver fillings when I started. I was VERY ill, but doctors called me dillusional, said it was all in my mind. I had the 'silver' removed from the 16 teeth that were affected and never had it replaced. One day, I may get the nerve to have the fillings replaced, but am considering just having all pulled and yadda yadda.
btw: a poster mentioned plates. Through out the years, I have used the plate zapper to zap my teeth. You use a speciman of teeth on the left plate. It really does work!
