anxiety
"For the past few weeks I have been having shaky hands and anxiety during work.  This isn't good considering I'm in the dental field.  I have no idea what brought on the anxiety since I have been doing this job over 10 years.  It was getting to the point that I feared going to work the next day.  I went in and spoke with my GP about this and how I didn't want to take anti anxiety medication, but I wanted something that would stop my fast heart beat and shaky hands.  She prescribed me propranolol for the days I worked.  Well I breezed through the first day no problem.  I took 30 mg in the am and did 10mg 7 hours later.  Tomorrow, I'm just gonna do 20mg in the am to see if it's strong enough.  This is the miracle drug."
