Unfortunately, it’s a deep seated neurological condition that cannot be cured. We can only MITIGATE it by implementing various strategies, whether that be a combination of: speech therapy, vitamins, medication, diet, exercise and psychotherapy is up to each individual. We are all different and our stutter affects each of us in different ways, both neurologically and psychologically. For me, I’ve achieved much better fluency by: avoiding caffeine, sugar, sleeping much better, taking a stack of nootropics, taking anti-anxiety meds, and on occasion taking other medication (beta blockers and relaxants) prior to stressful speaking events. Even though I do all these to improve my fluency significantly, my stutter will always be there. I’ve accepted that. I just do things to maximise my fluency as best as I can so I can function in the world (I.e work and social gatherings etc).
