Then you are the troll and you are lying again. I have never said you cant improve fluency. I said you cant cure it like you are claiming. That is a scientific fact. There has never been a adult in history that had a severe stutter that has cured their stutter. Even speech therapy doesn't claim they can cure it. Of course I am gonna make fun of some random redditor that claims that they achieved it without offering any method or proof. You are a grifter just like people that say if u buy this supplement you stutter will be cured
