This is exactly the teaching of the McGuire programme (also stated by u/sonfufon) which is taught to by stutterers to stutterers all over the world. There are even books in the subject. I am glad that it have worked for you. I use the same technique and it is the only one that has helped me control my stutter. I still stutter but it is on my terms. Could you please add an edit to your post that this is also called McGuire technique so that anyone that might be interested (and of course yourself as well) has an easier time finding guidance and proper places to look for help? Edit: why am I getting downvotes for this? I am just trying to make it easier to find info on a programme that has helped a lot of people, which are the techniques that OP are using.
