It takes a while, and it's different for everyone. Nobody is clear in a 30 day cleanse. Some think they are, then they spend years working other health issues, probably related to still to parasites. I have seen some post pics of what they think are candida strings, and I am positive it's roundworm.
If you add raw garlic to your cleanse, it may help speed things up, and I know it's gross, but sift through your stool so you know what you are passing. And keep cleansing till you are better, and when you are better, still keep cleansing to make sure every last egg is hatched and gone.
