My mom thinks she has to go to the bathroom every 15 minutes or less. She feels like her bladder is full and that she will wet her pants. Her doctor doesn't want to give her anything for over active bladder because of the side effects. She is wearing herself and me out walking to the bathroom over and over and over. I have her wearing depends to bed at night. She hates it, but I can't get up every few minutes to take her to the bathroom. Any suggestions?
