I think your interpretation of the flush is very possible. I have actually been thinking along the same line. I have done 2 flushes and a lot of reading in the last two weeks. It seems like there are a lot of arguments either way. I am skeptical, but I am very interested in peoples results.
My doctor has found a gallstone, but he's not convinced that I have "gallstone disease" because my gall bladder is not swollen. He give me the typical answer, "Well, I don't know why you have pain, but I can give you some drugs to help the pain." Does the concept of healing people ever come into a doctor's mind? If I keep complaining of pain then my doctor said he would take out my gall bladder, other wise he would not recommend it.
I am not interested in living my life in pain, nor am I interested in donating my gallbladder to the medical community. So, I'm trying the flushes. I don't see how they can hurt. I plan on doing 10 flushes. If I don't see any results by then, then I'll try a chiropractor or maybe acupuncture, anything but surgery.
I don't know how the flushes work, and I don't really care in the logistics of it as long as they work and don't cause any damage. There are too many stories of people having improved health that I can't ignore.
