So, did you answer the 3 questions in your new group as well as April 2014?
Ah, just found the questions in question.
What I did wrong: I got cocky (I know, NO SHIT, right?). I didn't grasp the principle of a lifetime addict, so I discovered the lapse/relapse syndrome the hard way.
What I could have done differently: I could have admitted to myself that I was, indeed, still addicted to nicotine. Maybe I knew, maybe I didn't, but I set out to prove that I was no longer an addict. Wrong move, asshole.
What I'll do differently this time: Posting roll call, and checking in with my fellow quitters to keep me accountable for my actions. This won't end on Day 100, 1000, or even 10,000. I'll mentor junior quitters and keep them accountable, just as they are keeping me accountable. I'll recruit new quitters from my workplace, and we'll supervise each other in person.
