The effectiveness of the book: "Stuttering & Anxiety Self-Cures: What 100+ PWS Taught Me" by Lee G Lovett Hello, there were many posts about this book, but I would like to ask if any of you have read this book, used the methods contained in it and reduced the level of your stuttering or recovered from it almost completely? If there are such people, please tell your story briefly if Lee helped you or not. I'm starting to read this book and I am curious if anyone has really benefited from it.
