The deodorant you should try is a "crystal stick" deodorant - you can buy them on-line or at the health food store. They are all natural and they are a deodorant sticks NOT anti-persperant - you don't want anti-persperant because your body should perspire - the crystal stick however, keeps you from "smelling" when you sweat.
They are great and believe it or not they last for YEARS!!
