hyperhidrosis
"I  have been using Drysol for 15 years.  I have figured out the perfect process for using the product. 



 If you aren't careful you can apply Drysol in such a way that it will cause extreme burning sensations and rashes.  Here's how to apply it properly:   Men, carefully shave the center portion of your armpits  to expose the bare skin.  If you look closely you'll be able to see the sweat gland areas of your armpits.   Apply the product only  to this area and not to the surrounding skin.  Do this right before bed and sleep all night long with it on your armpits - should keep you dry for 3 to 4 weeks.  Do this multiple nights in a row for a longer affect.  My dad totally cured his hyperhydrosis by doing this every Night for two weeks."
