I used to get infected once in a while but after taking kefir I hardly get it. I discovered that it was due to the pantyliners. Even when I changed the pantyliner during the day I still got the infection. Stop using pantyliners if you are using one.

Why don't you try taking kefir or yogurt.

Yes store bought ones are very sweet. I make my own; they are plain and sourish unless you mix with fruit juice. I use kefir in some recipes too. You could try making kefir or at least yogurt; those sweet stuff are not good when you have yeast infection.

Please check out my thread on kefir.

Panty liners encourage bacterial growth because of dampness.
