Besides keeping yourself clean of parasites have you done any testing for toxin build up? If not you may want to buy or build a synchronizer and find out what toxins have built up in your body then do whatever changes need to be done to get rid of them. Dr. Hulda's theory is that the parasites are attracted and maybe even in some type of symbosis relationship with the toxins(chemical or metal) in our body. So even if you get rid of them you are more likely to have the same problem again if you haven't gotten rid of the toxins.
