The science behind stuttering is a mystery to me and it boggles my mind how I can’t figure out in exactly which circumstances I tend to stutter. Although I have noticed that after I practice breathwork my stutter is pretty much gone. Maybe it has to do with oxygen. Maybe it’s the relaxation of the muscles in my tongue. Maybe it’s the state of mind. Anyways, I would love to hear your thoughts. Well done on writing a manual, very thoughtful of you.
