When it comes to deodorant it is hard for me to find something that works. Im not sure if it has something to do with the CF or not. Ive been having to use the store brands of clinical protection. These are really bad for you but I felt like I had no choice since the store natural brands didn't work. I finally found this on ebay and it works for me. Im amazed and excited! I wanted to share it with you all because a lot of people believe there is a correlation between deodorant and breast cancer. I try to prevent any other diseases as much as I can since CF is enough to deal with. Just food for thought and something to think about. http://www.ebay.com/itm/180991500839?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649
