Soo, I had to go the natural route. This is what helped:
-cutting out sugars, sweets, refined carbs (white bread, white sugar, etc). Yeast, like most fungi, feed off sugar.
-exercising regularly, which for me, meant running
-eating yogurt with live and active cultures
-showering daily and wearing cotton pants and panties (I do it anyway, but thought it worthy of mention)
I had been suffering from the YI for a week and within 1 or 2 days of following the above regimen, it totally disappeared.
Hope it helps someone without access to their YI meds! For some reason the gentian violet or yogurt suppositories don't really work for me.
