I don't know what you have tried, but are you taking probiotics? One of the candida diet's goals is to turn your body's ph more alcaline again. Lots of chemicals, alcohol, sweets, cheese, etc. create acidic environment in the body.

I did beat my recurrent yeast infections. I was clear for more than a year , but then I started eating carbs, splenda, and all kinds of c*** and I am dealing with the yeasty beasties again...
I seem to be very sensitive to processed food and chemical additives in food...
