Thomas3.20.2010 YES! That already happens - I run out of air sometimes at the end of a long line. One of the things that worries me a little (I hope for the best this time) is my voice. Once before when I quit, my voice changed and I didn't like it. When I started again, it went back to being what I expected. I don't know what that is all about.... Anyway, I am on my 7th day now and feeling really good about the quit overall. Thanks for your feedback!
