Have you tried "depositing" yogurt in the vagina? I've been using a douche bag with a little yogurt and depositing it every day, as I struggle with BV and candida also. It takes a awhile - 2 weeks before I saw improvement - but it has helped.
I imagine I will have to do this until and unless my whole body is someday rid of candida, but attacking it from all ends (!) seems to be helping...I'm considering a yogurt enema.
