I had had hyperhydrosis of the whole body pretty much and got surgery (I believe it was called a parasympathectomy, or somehting like that), It made a huge difference with the hands, face, pits, and feet, however, it made me sweat more form my back and chest (it's called compensatory sweating). All in all though it was worth the money. By the way I tried drysol with very little results and I heard the shock thing is snake oil. Botox is the only other treatment I know that works. As far as systemic sweating you can try anti-cholinergics (usually used for bladder control problems) to decrease total body sweat but it will make you over heat if your not careful like DR. D said.
