Okay, that lets me understand where you're coming from more. So you understand 'cure' to mean like some penicilin for an infection or something - basically no work involved. My dad's speech as of now, is so clear that you would never be able to tell he has a stutter except if he drinks 4-5 cups of coffee then you can hear minor discrepancies. I've always been on the side to call that as not having a stutter anymore.
