Sorry you are suffering. Candida is hard to kill. I have to recommend that you buy Dr. Clark's newest book "The Cure for HIV/AIDS"
In this book, the answers you need are well explained. It looks like it is going to take a serious effort to erradicate.
She has had success curing Candida using parasite herbs and plate zapping which is a more sophisticated way to use the zapper. But it is very well explained in the book.
Also, I would recommend that you look up Hydrogen Peroxide therapy treatments. This therapy you take drops of food grade hydrogen peroxide 3% in water. You start with 1 drop and increase gradually.
