hyperhidrosis
"I have been using Drysol for close to 16 years now... I love it.  My story is very similar to several I have read on this site.  I had a terrible problem with underarm sweat - to the point of putting wash cloths under my arms.  It was so bad I could not wear sweaters in the winter because I would soak them.  When I started using Drysol I had the typical itching and burning for a few weeks.  The more I have used it the less the problem.  Now, I only itch if I get too far out from under my arm pit and put the solution on skin not used to it.  When I first started using Drysol I was an every other day user.  Now, in the winter I can go 6 to 8 days.  In the summer I go 3 to 4 days - I live in Atlanta, GA and we reach 98 yesterday."
