I was lucky in that I am a speech pathologist as well as a lifelong stutterer. I was lucky in the sense that I knew where to look to find the “cure”. I found the cure studying fluent speakers and by asking the question as to why they don’t stutter. I found the answer in the Valsalva response as it relates to stuttering. I found that when you have the ability to voluntarily control the airflow through your vocal folds during speech you can become fluent. What I did was to rewire my brain to match the brain that of a fluent speaker. I now no longer stutter. It has been a life changing experience. Try looking at books by William Parry about the Valsalva response as it relates to stuttering. This is how I started.
