hyperhidrosis
"I've been using Drysol for about 15 years and it has changed my life. I went from always having to wear black and/or jackets all the time to having absolutely no more sweating! I followed the directions to a tee, but after a year, I started to cut back on my use.  Now, I only apply once a month and it works great.
Tip....Make sure you don't shave your armpits for at least a couple of days before applying and that will alleviate any tingling or burning."
