if your tongue doesnt' get all coated after drinking the apple juice you're probably okay. You can dilute it, drink 50/50 apple juice/water. Also, take the saliva test to see if candida is still running rampant.
Oh and did you ask about leaky gut - how to cure - earlier and I forgot to answer? The only way I know of is to keep the colon as clean as possible with daily enemas so it can heal, much the same way you'd clean a cut before yuo band-aid it.
You have to avoid eating all allergans for at least 3 months so your body no longer thinks of them as allergans. If your colon isn't too dry, you can take liquid chlorophyll both orally and in enemas, and take aloe vera juice, 1/2 cup 3x day. These both speed up healing.
