hyperhidrosis
"Have been hiding excessive sweating for ~2 years now ... didn't sweat at all after the first application of Drysol!  It did tingle/itch for about 15 minutes, but definitely nothing to stop using it for!  On day 3 and haven't had a single drop of perspiration and have not had to use another deodorant (although I think I might get one to dab on in the mornings just to make me feel better. BEST PRODUCT EVER."
