I don't think coffee is fermented, but I KNOW green tea is not.

Something else to consider...um...well, I had a relative, male, who often struggled in the same way and thought maybe his wife was giving it to him. After dragging her to the doctor, he discovered it was HIS blood sugar. He was in the early stages of diabetes. As long as he kept that in check, no more chronic yeast infections. I hope that's not your problem, but it could be from elevated blood sugar levels over the years. It may not even be high enough to be prescribed any medication, but just something to keep in mind and extra motivation to eliminate sugars and wheat from your diet.
