Sorry to here you got thrush, unfortunately, it is all to common with this treatment. I had it four times. Diflucan works but it does take time. For me 3-4 days. The last time my ENT wrote a scrip for doxy/nystat/HC/qdrl. It a swish and spit stuff. I found it very effective and quicker than diflucan. He gave me three refills and said I could self medicate when I felt the first signs, which was burning tongue.
