title: On call.  I am a 38-year-old junior executive.  My work gets good marks from my supervisors, but I have a problem that may hamper my career.  Every time I have to make a presentation, I get terribly nervous, making it very hard for me to get through my talk.  I've heard there is a pill that can help, but I don't want to take tranquilizers.  What do you suggest?
