I used P&B shakes for a while. I did get something that I think may have been mucoid plaque but after that I got sicker and sicker. I stopped the P&B shakes but did not improve for months until I started treating myself for leaky gut with glutamine, slippery elm & fish oil.
I think either the removal of mucoid plaque exacerbates leaky gut symptoms or once mucoid plaque is removed the P&B shake scrapes off the healthy mucus layer leading to further illness.
