To EPP, Thanks for the reply but what do you mean substantial results? Have you eradicated the yeast? I have sytemic yeast not just yeast in the gut, I also have leaky gut syndrome. I don't want to buy something and use it for several months just to find out I should have gone a different route. The first person I talked to (that was a rep) said she had never had yeast in her life but was telling me it worked but she herself had not used it. This didn't impress me. I would appreciate any info.
