It's a sweaty kind of summer this year.  And while the multiple
days of triple-digit temperatures have made some people glisten
and others drip, everyone seems to be seeking ways to dry off.
Some are showering more or slathering on "clinical-strength"
antiperspirant.  Cosmetic surgeons are injecting Botox to block
the nerves that stimulate sweat glands. And a procedure offered
at a small number of hospitals locally and nationally snips
nerves to offer a more permanent solution for those with extreme
cases.  "Everybody is supposed to sweat to some degree," said
Dr. Mark Krasna, a thoracic surgeon at St. Joseph Medical Center
in Towson, Maryland, who performs the operation, called a
thoracoscopic sympathicotomy. "It's one way the body regulates
heat. But we all know friends or relatives who sweat more than
others."  A normal amount of sweating is about an ounce and half
a day, or enough to fill a shot glass. Those with excessive
sweating, called hyperhidrosis, can produce four times that
amount or much more. St
