Please do tell what "this" course was. I for one have stuttered my whole life, and have seen speech therapists since I was 6 or 7 (I'm 24 now). Each one could not determine the underlying reason that I stuttered, and pretty much chalked it up to nerves (this scares me because how freaking nervous do I have to be that I don't even realize I'm nervous anymore, lol). Despite the fact that I don't stutter when I'm legitimately happy, I still yearn for ways to prevent it in all conditions.
