excitement and anxiety induced stuttering

excitement and anxiety induced stuttering hi all, there were some incidents in my life where i stuttered too much in front of everyone and all started laughing and blah blah...these incidents just come to mind whenever i try to speak in public so its hard ....these situations get too intense that even before speaking i feel by BPM going through the roof and i am super excited i have noticed that whenever i am more calm and less excited i stutter less or its almost negligible ... i try to cool myself down during conversation but its a hit or miss... can you suggest some methods to control this anxiety or be more calm during conversation or can any medications help ?
