I did my first flush then started an anti- parasite regime that had an internal sweep fiber drink with it. 15 days later, did the the second flush. What a difference it made in the way my body handled the flush. It was realively painless with elimantion being a breeze. Now I'm getting strange looking critters in the toliet bowl 2 days after the flush. Nobody likes to believe that they have parasites. But it's a fact.
