The same thing happened to me when I took Grapefruit-Seed-Extract and Fungal Defense. But I had it even worse (the painful cystic kind) when I took some powerful probiotics.
I think it's inevitable that we'll absorb some of the toxins, but breaking usually means you're killing too much at once for the body to properly handle. So even though you are doing enemas, it just not might be enough. Try lowering the Paragon dose. Maybe take something like Colosan or Oxypowder at night too. The oxygen keep you eliminating as well as providing an unsuitable environment for the parasites to live.
Don't forget to replace the good bacteria after the cleanse. VERY important.
BTW, I only break out during a Liver-Flush if I don't clean out my colon afterwards. I never flush w/o getting a colonic the evening after the flush.
