All i can say is i had surgery (T4 cut) in March of 2004 and am very satisfied. hand sweating is 99% reduced and foot sweating also decreased by probably 75%. Yes, i do have some CS from my chest down thru my legs but it is very mild. living in Alabama, i didn't know what to expect from our long humid summers, but i didn't notice any real difference from before...i mean, in summer time you start sweating as soon as you step outside anyway from may to september, now i just don't sweat from my shoulders down thru my hands
