Damnn this is gonna be hard considering all I’ve experienced as a stutterer. I’d say best experience had to be taking shrooms as it cured my stutter in a sense. I remember I was with friends and we were relaxing and conversing to one another. My stutter seemed to just vanish and I was talking the best I ever have.Its an indescribable feeling. Worst experience had to be when I was called on in class and I stuttered terribly through my whole response, no one laughed, but I sensed this awkwardness in the air. Everyone must’ve been like wtf .... That’s why I believe depending on the cause of your stutter, it can be cured through decreasing anxiety and stress as these for my are the underlying cause’s of my stutter.
