I was terified too! I have almost completed 2 weeks of the colonix and paranil parasite cleanse, and have not been too freaked out. I am doing the Colon Cleanse and parasite cleanse at the same time, and have not had any problems. I have heard good things about the Clarkia , I am using Paranil and have had good results. I am not sure what Colon Cleanse Dr. Clarkia recommends, I have good cleansing with the Colonix though.
I have heard the benefit of doing the Colon Cleanse at the same time, is it helps flush out the critters. Make sure you drink lots of water. I also put drops of liquid oxygen in my water 2-3 times a day. I heard it creates an oxygenated environment that the critters can not live in, increasing the effects of the parasite cleanse. Anyway, good luck and happy cleansing. Cindy
