Hey there! Like somebody suggested, anti-anxiety medication can be useful to somebody who stutters. I spoke with my GP about starting medication at the end of July to help my stutter. My stutter/blocking sounds similar to yours in the fact that with my mother, my husband, and my co-workers talking casually... I don't really stutter! However, stress, work, or phone calls put my anxieties at a high level enough to exacerbate my stuttering and blocking. It got to the point where my stuttering was really impacting my job and any prospect of moving up in my career. When I spoke with my GP, she was very apprehensive about giving me Xanax for reasons I definitely understood. Through past experience, Xanax did give me temporary relief, but I felt myself developing a dependency on it in order to not stutter. It was very much temporary relief and my GP wanted me to be on something I could take long-term since my anxiety has been long-term, and is something I have to work on for the rest of my life. I was given .10mg of Celexa to take every night, and I can say it has definitely helped and improved my stuttering overall and several people around me have noticed it as well. I am at a point where I feel that I may ask my GP to bump my dose up a bit, but I want to keep an eye on my stuttering and anxiety overall for a little while longer. I think a long-term anti-anxiety medication would be more beneficial to you, but it's important to be very frank and upfront to your doctor when that time comes in any case.
