I didn't start the Zymex 11 until I was quite a ways into killing the parasites with the Barefoot dewormer. Say a few months. NO, I didn't feel good; I felt like crap for a long time while I was killing off the parasites. It hurt really bad in my liver. My colon hurt. It all hurt for a long time, but NO drugs. Absolutely NONE! Use the Castor oil pack as this will get the bugs out of hiding and it will help a lot with the pain. Use it all night if you have to and put a heating pad over it on low or medium.
The Zymex 11 digests the tapeworms. You won't see a whole lot of the remains of them. I did see the scoleces of 3--that's the head without the innards in it, plus some of the slimy, transparent tail that was mostly digested.
