hyperhidrosis
"I am a 40 year old male who since I can remember, would sweat excessively under his arms.  It does not matter if I was stressed, if I was hot, cold, etc.  The worst is when it's 20 degrees outside, I'm freezing, yet my shirt is soaked under my arms.  That drove me nuts.  I used to sit at work, and keep a stash of paper towels at my desk that I would sit under my arms so that the sweat marks would be less visible.  Black was my favorite shirt color, especially on days when I had to present to a room full of people.  I applied Drysol the first night and the next day, 100 percent dry!  I feel like a new person!  I can wear tighter shirts and I can even wear grey!  There was some discomfort after applying, but it's well worth it, in my opinion!"
