Julie, I agree with Raster with the SF722, these guys seem to know there stuff. No health food or vitamin store in my area carry this. I need to order it online. The doctors that diagnosed me with digestive yeast called it thrush although my tongue was not coated but my gums seemed to be turning white. After being on the diet for 5 months I slipped up a few times and my first symptom was night sweats and on/off sweats during the day. Also ears start ringing. The ear ringing seems to be the first to start. You do need to either take the SF722 or prescription antifungal. I am not sure if you can take them together. And Yes, I still battle the yeast but not like in the beginning. It is a very long time to get this under control. I guess it all depends on to what degree you have this.
