That is so true and I relate a lot. I used to smoke a lot of weed for my stutter, learned 2 things from it - the way I talk and how fixated I am on my speech. I stopped using weed for it and tried to simulate what the weed gave me - I relaxed the way I spoke and let the words come out without putting in much effort. I get in the hang of using speech techniques until I do it subconsciously and I can talk without overthinking it.
