I have no idea what that zapper is---but if you feel a deep strong numbing sensation while starting to use it, stop. If you purchased it here, it's probably got some of the frequencies the 'elites' are testing that target humans. RHE worst I ever felt in 15 years of zapping was a very mild tingly sensation.
Are you reading Dr. Clark's book for proper usage with the herbs? Do you know what indicators of success you'll be experiencing. Learn those before running around half c$%ked (again?) hollering 'it didn't work, it didn't work' because I'm aware that's what this all could be about. Benefit of a doubt, though.
