Stuttering to me is like something that just "happens" to me. Ive posted about this and have discussed this in the comments a few times. Heres a post i made on this exact topic: https://www.reddit.com/r/Stutter/s/KOaTqdSgne Essentially, stuttering occurs without anxiety, with anxiety, no confidence, or full of confidence. Its almost like there are underlying things occuring in the brain that people in this subreddit choose to ignore. Not everyone, but a few vocal few. I made another post about dopamines role in stuttering too and that is what will serve as the main mechanism that we can address stuttering. The issue is that the same medication may work for some but not for others, thats because stuttering can occur from high dopamine, or low dopamine, and what your levels are may be different to mine. That's why antipsychotics work in some but not in others.
