14 years ago I had surgery to help get my hyperhydrosis under control. I had excessive sweating of the hands, feet, and underarms. After the surgery, I know have compensatory sweating. I literally sweat from the chest downward. To me, this is a problem for worse than what I originally was dealing with. I have been taking Ditropan for approximately 10 years and can honestly say that I can tell a very noticeable difference when I do not take the ditropan for a couple of days. If I can provide any further information, feel free to contact me at ronnie299@hotmail.com
