I have always had huge issues with yeast and have tried everything mentioned here...I now douche with this:
NutriBiotic, GSE Liquid Concentrate, Grapefruit Seed Extract, 2 fl oz (59 ml) - iHerb.com
70 drops in 8 oz. of water. I think it has antifungal properties and it keeps my ph where I need it.
Also my gyno said if you have real issues with yeast, all the yogurt in the world won't help...your stomach digestion, maybe, but where you need help is far below that. Too much stomach acid gets to it. I stopped taking my acidophilus for the same reason.
You are right, no more antibiotics, I avoid them like the plague. But you can eat sugar...it's only diabetics who can have yeast issues because of sugar (checked with 2 gynos on that one.)
Also, I am not having sex right now, which makes things a WHOLE lot easier down there. However, my yeast issue has been different with different people I have been with...
nonexistent to could not make it go away!
