I think everything has been covered but I just wanted to "second" a couple of things. First, the water issue is a must for my poor DH. He has had to have the surgery to blast his twice in the last 5 years and it is all just SO painful. For us, evidently our tap water is a problem so the DR recommended bottled water. Also, I have heard that the cranberry pills do work for some folks. The biggest issue is to make sure she is drinking PLENTY of fluids. Good luck...I hate to hear she is in pain :(
