I read that someone passed 3 inch liver flukes, I got rid of a couple that were all of 2 inches, and was mortified. You mentioned about your neck, and that is one of the major symptoms that I too have been dealing with over the past year. since this 2nd round, it has disappeared. And, the black tough stuff that you wrote about, is what I always thought was mucoid plaque. That is what I've been seeing this time around. Cleanse ON! momo
