There’s a lot here. I’ve seen you trying a lot of exercises that are going to make the problem worse or do nothing, so that’s good news. I feel that if you try the practices/habits as I described, you will notice a sustainable difference. The thing about there being no cure is this. you have to understand that some ppl who stutter only have repetitions/prolongations, *no blocks*. The reality is that every human who speaks has repetitions and as long as they are infrequent and they flow easily to your next word, they are no a problem for the speaker or listener. (You’ll learn this quickly if you try the steps I’ve outlined). While you will always have occasional repetitions, you can almost definitely dramatically and sustainably reduce your blocks. There’s no such thing as perfect speech. Listen to any famous politician or speaker and you’ll hear imperfections. Medications - don’t worry about there not being one bc if there was, it could have bizarre side effects and only address part of the issue. Let me know if you have any other questions. I’m glad to freely share my experience if it can help others
