How can I stop hyperhidrosis?

Go to a dermatologist. Well I have hyperhidrosis more on my hands but yes I have it on my feet and underarms a bit. I'm a girl so It's extremely embarring but I got this thing Drysol..It's aluminum chloride and depending how much you sweat the higher the percentage of it. Its suppose to clog your pores or something. Sorry for being too informal, look it up online I think you will find more info on this product.
