Thanks for letting me know about the zapper. It does make sense that not all of the parasites are in the digestive tract and I would need another way besides the herbs to be able to get to them. I did not know I could download the book for free from this forum. Thank you so much! That will save me a few bucks. Well I guess I have been doing half of Dr. Clark's parasite cleanse. I will have to check into making my own because there is no way I can afford to pay the price I saw online. Good to know the LBBB won't hinder me from using it. I couldn't sleep last night because of all the itching and did a little research on that and found pretty much the same thing you said about the older pace maker.
