I'm also in Texas. I don't know if this will help settle it in your mind or not.
What I saw was tapeworms, and I never claimed to know which part of my body they came from. But the cleanses were too close together and the Tapeworms seemed too long to have grown in the time between.
As far as the zapper technology, using frequencies on organisms is no stranger to science. In fact, dermatology has just started using a device called the zeno which is based on the same principles as the zapper. It is basically the same thing as a zapper. It is used to kill bacteria on the surface or just below the first layer of the skin. Of course no credit is being given to pioneers like dr. Clark or Rife. The same frequency priciples are also being used in warfare to temporarily paralyze whole enemy battalions.
It is good to be skeptical. A word on Hulda Clark though, she knew that she would eventually be prosecuted which is why she published her own books and copywrited them is such a way that anyone is allowed to copy the book and post it anywhere free. All the pages of her books can be read on the internet for free. If someone were just out to scam the public for money why would they allow this? Either she believes in her research even if its false or wrong or she believes in her research and it has truth. Either way if you have read all her books cover to cover you will see that she believes it is true. Yes she has been prosecuted and defamed but secretly the Science world has listened and taken the credit for her research elsewhere.
