I had one three yrs ago, and was supposed to go again two months ago. I cancelled it. the zapping was what bothered me. I could handle the sticks with the needles, most of them, I couldnt feel. the electrical current however...bothered me as much as chewing on tin foil with your teeth. I hate shocking sensations. Particularly when my feet were icy cold, as they usually always are. I pray for the day they develop a much more suitable test for everyone to "enjoy"
