Good morning. My daughter suffered with this for years. Same sceniaro. Doctors gave her all of the same medications you were given and she tried all of the holistic things you mentioned, including the diet. I convinced her to see my acupuncutrist. He told her that recurrent yeast is an immune system issue. She has been seeing him for the past 9 months and no yeast infection. I know how frustrating and upsetting this can be. I'm not sure how you feel about acupuncture, but it has helped her tremendously. I also go for vertigo and have had great results. Good luck on your journey and I hope you feel better soon.
