Bette, don't mess around with bladder infections. I drank cranberry juice when I had one which masked all the symptoms. I felt fine for a week or so then developed a fever, nausea etc which I though was the flu. After a few weeks of that and several trips to the doctor (who never suspected a UTI because of the flu symptoms) I eventually got so ill that I had to go to an ER --there they discovered I was in renal failure. That did huge damage to my kidneys but I just barely avoided having to go on dialysis. Now I call the doctor at the first symptoms and have an RX for antibiotics to carry around with me everywhere (didn't bring them to Africa and sure enough, I had to have the doctor come to the hotel--but he was cute, so it ended well). Anyway--don't mess with cranberry juice if you have UTI symptoms--go see a doctor. Editing to add--but drinking cranberry juice in a cosmo is a great thing!!!!!
