Several months ago my Dr. put me on 100 Mg of Diflucan 1xday for high yeast levels. The first few doses gave me serious tummy issues. But after several doses it leveled out. I had been in a severe flare that lasted 5 months. I believe shedding the yeast build up definetly helped end that flare. I have started taking the Diflucan again, however this time I have not had any tummy issues. My question is...how do you know that the Diflucan is working, and should I be taking a higher dosage?
