Flying for the first time at 67

I have friends in Florida and I've run out of excuses to visit them. The flight is planned and we're leaving Tuesday after Easter. I know I shouldn't fear it and in my mind I know I need to man up and do it. But I'm consumed by the fear of flying. My wife thinks I'm going to back out but I can't disappoint her. Thinking about calling family dr. for something to calm me, or maybe a couple cocktails before the flight. Any suggestions?
