anxiety
"Not sure if this qualifies as an anxiety attack, but not sure what else to call it.  I'm 60 years old and have never suffered from anxiety or depression in the past.  I'm active, lift weights, and train (a lot) to race competitively on bicycles. Almost every morning, driving to work (I'm a CFO), when I get about 20 to 15 minutes away, I break out in an uncontrollable sweat.  I'll turn the AC on to 60 degrees turn all the vents on me.  Still, by the time I get to work, my clothes are soaked!  Doc said it seems reasonable to consider this an anxiety attack, regarding my work situation (it can be stressful).  The sweating happens with incredible regularity.  Klonopin made this go away. "
