Eating yoghurt wont do much for a yeast infection - try putting it up your vagina at night - very very soothing. Or go to the chemist for a thrush cream - they work wonders too. I have just got over 5 weeks of a severe yeast infection - had nizoral tablets and two weeks of nilstat cream morning and night. Cranberry juice is also very good as well even though it tastes revolting. But what ever you do dont put a garlic clove up there (looked up natural cures for thrush on internet and said to do that) - worse mistake ever - reeked of garlic the next day and made everything 100 times worse!!! My doc had a great laugh over that one!!!
