Interesting, where did you learn to meditate? I have read studies where its phenomenal for us. Sorry that last sentence has an error; Did you mean you only spoke well for one day after a week long of meditation or do you see persistent fluency thereafter. I practice yoga but its not much for the meditation but the stretching. My stutter is mild at this point and I find that certain mind sets increase fluency by a lot but its hard to stay in that mind set. I would assume meditation could help a lot.
