What helped reduce my stuttering was getting prescribed to citalopram (generic Celexa, ssri), it took about two months to take into full effect but it lessened the anxiety that came on whenever I talked to someone (especially at interviews, door to door surveys, to people of authority, and when I was wired on coffee). I need to get back on the meds because I have been off of them for almost two years now. I've noticed that my social anxiety came back.
