to all women with uti problems...I had uti problems a few years ago...I finally figured out that they were coming from a water cooler at work...people who drink from these need to know when and how often it is cleaned...I realized when a maintanence man changed to bottle for us...he asked how often this was cleaned...everyone stood around..."I don't know"!!!!    well the inside looked like pond scum!!!!  I have never drank from a water cooler again....and have not had a UTI since...!!!!
