masturbation changes my stuttering, i'm taking a test and i'm currently in 3 months without doing it, in the first month the stuttering improves a lot but then it seems to come back. Some people have also said that coffee seems to make stuttering worse, I am currently giving up coffee to see what happens. And finally, I realized that stuttering is like self-hypnosis, it's like you intertwine your fingers together, close your eyes and say to yourself "they're glued, so glued I can't separate them" and so open your eyes and try to separate them, if you believed what you said, your fingers really won't separate, it's hypnosis. Stuttering is almost that, it's like self-hypnosis, you try to unlock your mouth, but it stays stuck, like finger hypnosis.
