hyperhidrosis
"Such bad sweating/leaking from armpits that thought I would give it a try. No prescrip required in Canada. Picked up the extra strength and used three nights in a row. Stopped my sweating 100 % immed after three nights.  Last 2 mths before I had to use it again. I now add an extra night every couple of weeks and no sweat from pits for over a year.   Yes, it can itch but remember to dab not smear it on.  More doesn't work any better and almost no itch on my 2 week applications due to using less.   Short term pain for long term gain"
