You are killing yourself with these treatment. You will end up with C.difficile or Candidiasis. I am not trying to depress you but yourself said where you live you can pick up H.pylori easily. So what is the point of taking these treatments which not only do not work as you state and your are a proof that they don't but they are making probably sicker and sicker.
Ask yourself this question: Why your family are not showing the symptoms? Why the hundreds of millions with H.pylori are not sick?
Doctors have no idea. They just like push patented drugs because there is money generated this way.
