I'm pretty sure I have candida. I have yeast infections every time when i get my period, and i also have a mercury overload. Although I've been battling this little monster for quite some time now, I'm hopeful that when i manage to detox the mercury from my body, that the candida overgrowth will subside. Have u looked into heavy metal poisoning? That could be one reason to why you never have gotten rid of the candida (if you have it).
