[I did](https://www.reddit.com/r/Stutter/comments/sv9dx9/comment/hxk0c2g/?utm_source=share&utm_medium=web2x&context=3). Completely, with an simple and stupid way - learning 相声, or massive talking (2 hours+) actually. Since I was cured of stutter in kindergarten (or maybe first or second grade), I didn't have any stutter at all, until I went to university. Then my stutter came back due to lack of talking, until now... This method might only work for me though, my stutter is not so common. I mianly stutter when excited, somtimes when socially nervous. If it's cause by excitement, it comes with forehead pain equal to the degree of excitement. Theoretically, if I can find a way to talk more every day I should be able to cure again. But I work from home, I don't have the need to speak a lot, and I'm too lazy to explore the need for speaking a lot.
