That's awesome. Hearing about vitamim B1 and magnesium takes me back to my teen days where I'd be crazily swallowing those down whenever I had a big speaking occasion, even though it didn't really work for me. I guess it became more of a ritual thing for me, as opposed to something which actually helped. The only thing I would say, if you didn't already know, is if you experience a lot of diaphragm contraction when you're not on the vitamins, then you still have a noticeable amount of fear from your old days. And this is developed fear. Little kids who are yet to experience the negativity of stuttering won't be having any diaphragm contractions. However, since this helps you and you're living your life, then that's a great success story!
