The short answer to your question is "yes." I have beaten Candida back into control. However, some of my research has indicated that some people, such as myself, have a genetic tendency towards fungal overgrowth. I'm not 100% sure of this yet, but I know in my case and others it seems that Candida is always something to watch out for.
I very much believe that it is possible to overcome many difficult diseases, including Candida overgrowth.
