you need tobe drinking cranberry juice(100%) and taking CS/IS every couple of hours for at least a week! My friend did this and she got rid of a very bad infection that was getting close to putting her into a hosiptal! The CS/IS every couple of hours is needed to combat the infection on a ongoing basis. My friend after a week had amazed her doctors by getting rid of her infection. She told them what she did and they did not like it! But her doctor told her to keep doing what she was! It could take up to 2 weeks to get rid of the infection.
