Congrats on a great choice. Cancer scares happen all the time. But the scariest thing about them is that you might get a clean bill of health (like you did) and think that means that you can have "just one more." That is addict-speak. And, it is bullshit.
Post roll, keep your word and repeat. That is the way to freedom.
Addicts are professional liars. We've lied to our families, friends, and everyone who cares for us. We even lie to ourselves. The most fucked up part is that we actually fool ourselves?!! Think of that for a minute...like a magician doing tricks on himself...and believing it?!! 'Crazy' That's how powerful nic is. But those days can be gone.
One quick point on your intro (which may have already been covered and I didn't see it). But you didn't "kick the habit." Bad habits are picking your nose, being late, talking too much (my wife), not listening to someone while they're telling you something (me). But neurotically poisoning yourself with something that will kill you is ADDICTION. Learn all about it. The folks on here actually know and understand addiction.
Bad news is that you can't "kick" addiction. You'll always be an addict. That's why you can't "have one more." But the good news is that you can control it. Go to the Quit Groups page and click around. Every name you see there is an addict. And everyone of us is controlling our addiction ONE DAY AT A TIME. And you can too. They all understand you and what you're going through right now. Cancer scares, funks, fear, anxiety, nervousness...whatever. We're all with you.
YOU CAN DO THIS, JARED!!! Post roll, read and repeat.
