I saw Dr. Piller in person. I lived in Moscow Idaho at the time, because i was going to school.
His wife is nice, but in all honesty, Dr piller looked worse off than me. he didn't look healthy by any means, and I took the Sf722, followed the diet, and took a magnesium calcium pill. He said my thyroid was fine (although later on i was tester to be hyper) and then i went at it. I never felt better, and i came back a couple times, and they even failed to send me the vitamins i paid for in the mail. I don't know, it was bogus i thought. And through all of it, i came back and said "hey i don't feel any better, but worse"... he looked puzzled and said "well, you don't even have candida".
It's good to remember, that Karens symptoms seemed localized. If it's systemic, i think it's a different issue all together
