Hello
I have issues with this due to the various crohns medications I take. I have found one thing to help immensely. I bought a make-your-own douche kit. Fill it with water and hydrogen peroxide. I do about 1/3 peroxide to 2/3 water. Hydrogen peroxide is a natural yeast killer and is inexpensive. I try to do this about once a week and have not had issues with yeast since I started. Hope it helps.
