Many years ago after taking a course of antibiotics I developed a yeast infection. That time, and a couple of times since, I have used salt in my bath water. Plain table salt, use liberally, 1 to 2 cups disolved in a shallow bath (to keep the salt more concentrated). The relief is almost instantaneous. I repeated the treatment once or twice and was back to normal. From what I understand, it helps to restore the normal pH of the vagina. It is quick and inexpensive. Have never since used anything else.
