Well, I think it's possible, but your just going to have to keep cleansing if you don't get rid of the toxins! Dr. Clark's research shows that parasites only come to a polluted enviroment. If we don't get rid of the pollutants, we will just get them back again. Make sense? Not everyone knows how to get rid of the pollutants, but I highly recommend every one to read Dr. Clarks book " The Cure For All Diseases " It would be really helpful for you as well, to see just why so many people keep getting them back.
