Tell your gastroenterologist that you have fibromyalgia because 40% of people with fibromyalgia will get IBS type symptoms. Only 2% have IBS in the general population. A gastroenterologist will usually concentrate of the gastric problems and not take into account fibromyalgia.
I have also trialled the Bob Beck protocol:
The blood cleaning didn't appear to have any benefit in me.
However, I did build a high power electro pulse zapper and the family were amazed that when it was applied to some moles on my neck which I had had for years they dried out and disappeared with 2 weeks. So there is something in this technology.
