I've ordered a zapper! What d'you think?

When I first read Dr Clark's book I thought she was, to say the least, a little cranky.(Pets raising Tapeworm eggs in the air, not using a hairdryer etc) Could I really live my life worrying about all the hazards facing me? When I read about the zapper I thought she had really lost it. However, I am a fan of her Liver Flush and I am beginning to think that a zapper might be a good idea. It is very expensive but I've ordered one and it has to be shipped to me in England from America. I daren't tell anyone I am going to give myself electric shocks with a battery - they will think I am totally bonkers. What can any of you tell me about the zapper. Does it work, what is your experience? All stories and comments gratefully received.
