Ive had cfs for 15 years. I was thinking of getting some metametrix tests done on the recommendation of a doctor who used to treat cfs. Has anyone had any experience with these? They are very expensive so i have to be careful as im on a pension. He recommended that TRIAD but im not sure as ive already had the allergy test done before. Here is a list: http://www.metametrix.com/test-menu/profiles/categorized Also, if there are any cheaper alternatives, pls let me know. I live in Australia. Im currently following drmyhills treatment protocol as best i can and have had great success with high doses of b6, vit c, magnesium, and i think chromium or selenium. Ive also been taking whey protein shakes every morning for years and cut that out 4 weeks ago and i was so sick!! I think it was a detox reaction. I also have a low, fluctuating body temperature and "borderline hypothyroid" as described by my doc.
