I think you should ask shelley some of your questions.
It does sound like you had a major yeast infection - I
am surprised that the dr didn't give you Diflucan or
something like it for this.
Everyone is different though. I have a systemic candida
problem, but have never had thrush in my mouth and my
vaginal infections are minor and infrequent. And yet, I
have major candida elsewhere to contend with.
Yogurt (unswetened, no fruit) is okay. MAke sure it
has the live acidolphlous added. You're smart to stay
away from sugar, dairy and wheat.
