Is there a good Kinesiologist near you who does muscle testing? Some chiropractors do it. I had a problem with candida and parasites and went to my chiropractor. They caused headaches, body aches, foggy brain, dizziness, and depression. He put me on Worm Squirm and SF722 and I had to completely cut out sugar, fruit, and juice. It took about 6 weeks of really following the protocol, but I was able to get rid of both. The parasites came back 3 times before I finally got rid of them. We found out I was getting the parasites from our dog and put him on Black-Walnut while I took the Worm Squirm again. Once we were both cleared I haven't gotten them back. We keep nail brushes at every sink and I always wash my hands after handling the dog or cleaning up after him, but apparently I am especially susceptible to parasites. A office visit with the chiropractor/kinesiologist shouldn't cost more than $60 max, though the supplements are not cheap.
