mance anxiety
"I have been in IT for forty years.  As I reached my late 50's my self-confidence began to decline.  My job requires me to do presentations regularly.  I started having serious anxiety and trouble getting through presentations.  My heart would pound.  My throat would tighten up significantly and my voice was weak and shaky.  My doctor prescribed Propranolol 20 mg.  If I take it an hour or so before a presentation I'm fine.  None of the symptoms I mentioned above.  Most work days I take it when I get up in the morning and I'm great all day - no matter what stressful situation comes up.  I was skeptical that anything could do what Propranolol has done.  It saved my career - and makes personal situations easier as well."
