Probiotics are great but make sure you find some refrigerated (herb store). These items are food, take a lot of them, they won't hurt you and it will go away fast.
Lots and lots of water. Lots of cranberry juice--not the cranberry cocktail.
Drinking lots of water, drinking cranberry juice, drinking tea, eating lots of yogurt for the good bacteria in it, and if you don't like yogurt you can buy probiotics at the pharmacy, it's just a pill form of good bacteria. You need to avoid carbonated drinks!
