I have done three parasite cleansings, still white ropes are coming out from time to time; especially, with liver flush, and enemas. I have done 21 flushes so far, and the last one resulted few pea size stones, and alot of tiny yellow ones-plus white ropes. It seems the parasites never ends. The P&B shakes doesn't work for me. Like you, I do have brain fog, and shoulder pain comes and goes.
