Infectious Disease department at my hospital suggested Kefir yogurt. Most physicians won’t recommend over the counter medicine or supplements but kefir has scientific study behind it I was told. Also, I was put on Dificid after my second bout when Vancomycin didn’t work. It’s very expensive so it’s not used as a first line of defence. 2 pills twice a day then one pill every other day for 20 days. A low roughage diet and no dairy, a probiotic every other day and so far, so good! I will gradually add more roughage. Remember…your gut is inflamed. It needs TLC right now. Hope this helps.
