I used a parasite program, ParaNix, from a company called Nature's Medicine Corporation based out of Fairfax, Va. It has pills for the parasite part and it came with a jug of Internal Sweep which is the fiber drink. And it also came with some senna tea that you drink at night but I don't have trouble eliminating so I don't use the tea. The fiber drink has psyilium in it and lots of other things. I haven't been brave enough to try the P&B shakes. The thought of drinking benonite clay just is hard to grasp. The P&B shakes may work better than what I'm using I don't know. But this seems to be working for me. It maybe more expensive than the P&B drinks but I like not having to decide on the receipe. Some like the P&B drinks just for that reason. They can adjust it to what their own bodies need.If you want the phone number for the company just email me personally.
