Pike - not trying to bring you down, because your enthusiasm is commendable. You need to adjust your thinking a bit, though.
You aren't fighting a bad habit. You're dealing with an addiction.
Realizing that was a key moment for me. It absolutely changed the way I looked at my use of tobacco. It helped me to realize that this is not something I can do halfway. It made me understand that I was going to go through some major mental and physical changes over the days, weeks, months and even years to come.
More than that, though, it helped me to understand that I can never go back. Just like an alcoholic, just like a heroin addict, I can't ever have "just one".
I am an addict. I will always be an addict. I can't control that, but I can control whether or not I choose to feed my addiction.
That's entirely different from looking at this as a bad habit. In all honesty, I think that's what makes the real difference between quitters, and people who just use the site to stop for an extended period.
