I feel for you. For a while, I was getting one at least once a month, and they would escalate into kidney infections very quickly. My doctor used to call me the Crown Princess of Bladder Infections (affectionately, I've been going to see him for nearly 15 years now). I quit drinking caffeine almost altogether and things have straightened up. I did think of something that might help though, I've been drinking a lot of that Emergen-C stuff that they make to help your immune system, and I got the cranberry flavor. I noticed it has a good amount of cranberry powder and the vitamin C has kept the yeast infections away! (I heard somewhere that vitamin C raises the acidity level in the body and makes the environment very uncomfortable for those yeast-y little buggers! It's worked for me.) Maybe drinking a serving or two of that will help. It's done wonders for me!!
