Do you release stones/old matter when you liver flush? Do you use a stethoscope to listen to your liver/gallbladder during your CE's? Tried Mag 07/ Oxypowder and a whole foods enzyme to help get things moving out? If your infestation is really bad maybe live/dead ones are blocking the biliary tubes? While I know CE's should help to signal the release of bile, if the small intestine is blocked by mucoid plaque or some other type of obstruction, toxins would be circulating in your blood. Have you ever had a colonic or high-volume enema?
Also, I remember reading in Matts protocol that at one point he was actually vomiting up worms. Do you check your vomit for signs of parasites?
From what I gather, the most optimal progression on CZ, due to what works for many is to
1) Effectively eliminate/purge everything from the bowels and heal.
2) Cleanse of parasite/candida infections
3) Proper liver/gallbladder/kidney function
I couldn't tell from what you've said, but it may be you have never effectively cleansed/healed your gut. Again, I'm not really qualified to make the dx but just a thought to consider. I've seen posts where people say it can take many, many months and even years to fully heal the gut. Some speak of passing mucoid plaque for months before it finally tapers off to normal stool as the healing progresses.
