I agree with crazybeautiful that the talking won't improve much. Yes, I'm much better than I was on day 1, but it never is "normal". I hate saying words like "green" and "screen", and I've tried to come up with words that mean the same but that I can pronounce

I have about a month and a half left with these things...and while I have grown accustomed to them I cannot wait until they are sawed out of me!!!
Best of luck to you...If you have further questions don't hesitate to ask.
