Query: don't use the one day stuff

My doctor told me never to use the one day yeast infection treatments. He said to use five or seven day treatments only. He said that he has seen many poor patients calling him, in terrible discomfort after taking this medicine. It is too harsh and the infection comes back worse than ever. Five day treatment is a happy medium. You will feel better after two days or so and the rest of the medicine will keep it away.
