I wouldn't say I've "beat" it, and it doesn't seem to me that a stutter that persists past adolescence can ever go away. (There's one study where some people in their early twenties reported that it was gone for good, but I probably would have said the same thing at that age.) But there is "[successful management](https://www.reddit.com/r/Stutter/comments/rbsg4p/succesful_management_agency_and_muchimproved/?utm_source=share&utm_medium=web2x&context=3)," and I'd say I experience that. I have no formal credentials; I just read 240 research articles and I explain what they say in layman terms. High-level researchers have read parts of the book and gave me minor corrections (that I made), but for the most part they were very supportive. I'm working on getting public endorsements from these researchers. I cite the studies in the book, so you (or anyone with the time) could go and read the studies and verify that my summaries match the originals. Also, the book isn't advertising for expensive personal coaching, or some kind of product that I designed (other than the book itself). If anything, I recommend people practice speaking with a metronome and go to cognitive-behavioral therapy.
