Hi Russ, Thanks for the info. I Do not have a zapper, I use a Beck Sota cs 
machine to make my cs tho. How do I make or get a low voltage treatment 
gizmo. The finger iseems to be developing more blisters today. I am very 
unhappy about taking this drug and prefef to rely on the wonderful knowledge 
that I get from my cs friends who helped me get rid of untreatable, MD 
standards, vertigo. Betty
