With stuttering, any “changes” usually work for a while. You’re going to forever be chasing that beast. Like for example, people have found that doing a fake ascent gets rid of their stutter….until you start to stutter in the ascent too. Remember the ear thing that supposedly got rid of people’s stutter? Well it worked for a little while until the brain got use to it and back came the stutter. In my experience, the only thing that has made me happier is accepting the fact that I stutter and being OK with it. More power to you if this all works for you but don’t drive yourself nuts trying to medicate the stutter away.
