Just a quick glance at it - I'm not sure this guy's course is the cure-all it claims to be. There is a bit more research out on stuttering these days about the common genetic markers that we all have as well as some progress being made pharmacologically by limiting dopamine in the brain with antipsychotic medication. I've never tried those so I can't speak to them. It seems like it helps but it's not a cure. Personally & anecdotally speaking, I tried a lot of therapies and met with a lot of different people as a kid, including a Russian scientist practicing transcranial magnetic stimulation mad and a mountain witch who read my fortune in Turkish coffee and cast a highly ineffective spell on me hahah. What I know to be 100% true is what can work for me flawlessly. At the same time, it requires so much effort and energy that I don't do it and continue to stutter. The only therapy that has worked for me was the Precision Fluency Shaping Program (PFSP) in Norfolk, VA. It's completely immersive, very expensive, and entirely incomplete. It works - so long as you go through the program and continue to not only do the homework 2-3x a day but also return for repeat courses until you iron every type of speech impediment. What took me a while to understand is that this program would be so much more effective if it also taught mindfulness meditation and the ultimate goal was maintaining crystal clear unattached awareness 90% of your waking time. Meaning, ascending to a Zen monk status hah. I don't know if it's possible to sustain this state. But I know that I was at least able to maintain perfect awareness of my speech-making body parts while in the therapy and reduce my stuttering to virtually zero (think, 1-2 short blocks at a problem consonant for every 1,000 words spoken). But that's the tricky thing with this recommendation - it's personal. Many others I met over the years couldn't crack the code like I did, or couldn't interpret the tools given in the same way. I think meditation is a great practice and you should do it. I don't think it will help your stutter unless you know how to control the motor tools behind it, which has to be learned in a clinical setting. I also don't think that the PFSP program will cure you but there is a chance it will help, especially if you click with the tools they teach, do the homework for the rest of your life, go back for a refresh session if you need it, and make meditation a daily practice. I'm revisiting my stuttering right now because I've enjoyed spontaneous fluency (this means uncontrolled, unintentional) for a while because I'm generally OK with social situations now. But when it comes to work, I'm not allowed to interact with clients... Without getting into details, it's so demeaning, disrespectful, and depressing. I can't speak a single sentence without stuttering through 60% of it at work right now. TLDR: Good luck. It's a hard road. Nearly impossible. There are many stutterers out there who get pissed when someone says "you can learn to control it to a point where it doesn't affect your life." I used to be one of them. It's possible, but it's an inhuman amount of work for those of us who didn't simply outgrow it when we reached adulthood. Very few people have access to learn the tools and the resilience to create a disciplined practice of daily training.
