Technically, just 3 percent of the population suffers from excessive sweating. But who wants to sweat at all? Certain Dri ($5.71 at drugstore.com) contains a higher concentration of the active ingredient found in most over-the-counter antiperspirants. Applied at night, it keeps you drier but not necessarily less stinky--so add a deodorant. Drysol, a prescription antiperspirant with a still higher concentration of aluminum compound, works better but can irritate your skin. This summer, the FDA is expected to approve the use of Botox injections ($500 to $1,500) to knock out the nerves that stimulate sweat glands.
