I was wondering of you have mercury fillings (silver, Alamgams)...these can cause many issues...You should look into having a hair analysis done. I was very ill and I am doing Dr Larry Wilson's protocol..helped me greatly in 1 year.
You may not have filling of mercury, but most people who suffer AF have high copper toxicity which causes severe issues.

He works with ridding the body of heavy metal and balancing out nutrition.
He does suggest supplements and diet through the results of the hair analysis,,,,each person have different needs. If you are concerned about the supplements causing more candida he suggests taking GB3 which help in many ways.
