Honestly I don't even need a cure to stuttering, just something in the form of treatment/medication to reduce stuttering. My stuttering seems to have gotten much worse since I have gotten older and some days man...some days its like talking like I am heavily drunk, or having an outright stroke. I hear some people on this sub find success with certain off label medications but in my personal experience it hasn't helped me all that much. Stuttering also seems very unique in nature where there is varying severities and varying triggers (different words/different situations where people are dis-fluent).
