Congratulations, Steven. There are many here who quit successfully after as many years of smoking so you will receive good input and support here. Please do stay close to the board, post often - historically, it has been seen that folks who do this tend to have a higher chance of success.
I would encourage you to understand triggers - there are daily triggers which you will need to face right away and overcome. They are the hardest as they will hit you often in the initial days e.g. coffee, lunch, meeting someone, going to the convenience store, gas station - all the little things that we do daily that we associate with a smoke. They are also the easiest because you get past them quickly within the first few days and become strong at overcoming the daily triggers.
Then there are the occasional triggers - a birthday, weekend drink, vacations, etc. These are things that will likely occur during the year and will catch you by surprise as you start to feel confident about overcoming the daily triggers. You need to stay alert and recognize that these are different and will need to be overcome using some of the same techniques used for daily triggers. This addiction is so insidious that it will want to you celebrate quit milestones - 1 week, 1 month etc - with ... a smoke. Be very alert.
Finally there are the life event triggers - losing someone, break up of relationship, job loss, surgery etc. We become vulnerable to going back to smokes when life hits us with these events. Smoking doesn't really help solve any problem but the addiction manages to overcome rational thought for long enough to cause us to lose the quit.
The trick is to recognize that we are addicts and will always be one so we need to guard our quit like a winning lottery ticket and not let anyone or anything take it from us.
