I am currently on the way to being cured of stuttering. It's all about changing your mindset and approach to speaking. You just have to find the approach that works for you. For me it is mostly about ridding the tension in my body, especially my shoulders and chest. And I have been reciting daily affirmations. It's almost like a form of meditation, and the positive thoughts become ingrained in your brain, and then you begin to believe. This allows the negative thoughts to begin to wither away, and then your brain can begin forming new neural pathways for smooth speech.
