Welcome to SAC!! I’m sure that the book is going to beat stuttering once and for all!!
The key to do it is to be very consistent, and work on the methods herein 24/7, until you master them, until you do them without thinking. It requires patience and determination, but you will definitely get there. A lot of us have done it, so you can also do it!!
I hope to see you in the SAM meetings!! (every Saturday at 10am NY time)
