I don't do that exactly... but when I am nervous, I end up tallking faster, blurring my words, and not make much sense... I know what I do but I can't stop it... it feels like he has got worse recently... makes me feel stupid for not being able to talk straight.

So I can't exactly relate (((((((((( Hope ))))))))))))) But I do understand that it's uncomfortable and can cause anxiety in itself... Hope you can find some way of alleviating it.
