For the 10 years that I was a smoker, the very first thing I did every morning was light up. I didn't consciously think about it, it was just what I did.
For the month or so I was preparing for my quit, the first thing I wanted to do every morning was smoke, but I delayed lighting up until my coffee was ready - and for the ten minutes I waited I just thought "I can't wait to smoke".
For the 10 days I have not been smoking the first thought of every morning has been "I want a cigarette". The second has been, of course, "I don't do that anymore", but nevertheless the inner demons still brought it to mind immediately upon waking.
But today? Today I woke up and made coffee and sat down at my computer and read some emails before I even thought about missing my cigarettes.
To my never-smoking friends, this sounds trivial. But to me it's a huge step forward. I'm only on day 10, but I'm definitely on the right track.
