ST. PETERSBURG, Fla. -- Imagine sweating so profusely that you destroy your clothes and feel embarrassed in public.

That's the curse of super sweaters, people suffering from a condition known as hyperhidrosis.

In moderate cases, the afflicted can usually get by with sweat shields, "sweatproof" clothing or strong anti-perspirants. For more severe cases, people turn to Botox, the same product used to reduce facial wrinkles.

When injected into the armpit, Botox temporarily blocks the chemical signals from the nerves that stimulate the sweat glands. The U.S. Food and Drug Administration approved it for treating excessive sweating, but it's not covered by most insurances.
