After I got my zapper, I bought a 9V battery, and I cut 2 6" copper pipes and attached the alligator clips to the pipe and hold them with a wet papertowel. It went away and came back, so then I tried to put one electrode on my throat. I did for like half a minute but it started to get painful so I stopped and just finished up with the next 2 7 minute sessions by just holding them in each hand. It hasn't come back, and when I went to work today everyone was complaining of a sore throat and stuffy nose! If they only knew...
