I have been there but i fell back because I spontaneously got into a anxious situation and felt a stutter and pushed true instead of stopping and imagining my diaphragm. I’m now doing it again and it is going so well. You are in charge of yourself you can choose if you use it or if you are to anxious what somebody else might think. Or if he has to hurry. You just need to have the 🖕🏻mentality. If someone does not want to wait that’s okay but don’t speak if you feel it. You can only do it if your shake is bigger less than your motivation. I was almost there and i was ashamed to take my time. I worked behind a bar for 2 full days without any stutter until i got ashamed this time i am not gonna let that happen
