You can eat and use yogurt but it has to be sugar free when treating a yeast infection. Sugar will only increase and feed the yeast infection causing your condition not to improve. I try to eat sugar free yogurt as much as I can even when those no fungus yeast infection present, and plus is taste good. Since many of you may not like yogurt you get the chemicals in yogurt in pill form which is something called acidophilus pills at a health food store. I mean yogurt is very good and tastes so at least try it cause you might develop a taste for it over time.  I should have gone to get doctors notes.
