So I've had like 5 UTIs in the past year. And I finally figured out what was causing them so it won't happen again...yay! But now it feels like my bladder is a little weak, I already take azo cranberry pills and vitamin c but what else can I do to strengthen it? Someone told me that holding your wee for longer amounts of time can help, but I've also read that doing this can cause UTIs!! Anyone have any tips?
