krampus - happy belated birthday!
I too have watched others struggle through the powerful hold of tobacco - my mom started at 14 and was not able to successfully quit until she was 66, though she tried for over 20 years)! It seems to be a lot like weight loss; there's no formula that works for everyone. Maybe like eating, it might help to figure out what you use smoking FOR - is it a habit of having something in your hands, the way the nicotine makes you feel, an image you want to portray, or something completely unique to you? Caveat: I don't know ANYTHING about doing battle with this - I am merely reeling off some talking points I learned when Mom was attending workshops, getting accupuncture, lasers, the patch, the pill, the jar of butts, and she would tell me what insights she was learning!

What finally ticked her off enough to quit was adding up all the money and taxes she spent on smoking, plus the costs of the typically twice-per-winter trips to the doctor to deal with respiratory infections. I kid you not - she literally could have paid cash for the two-month tour of Europe she's always wanted to do. It adds up freakishly fast!
What I can offer up are some thoughts on being stuck with looking backward. IMO, the only good thing to be found there is identifying what was going on in your life and your head when you were on target. Beyond that, I've learned that time spent dwelling in the past is just time that you can't spend taking action to make things better. This is a major theme of 2012 for me; it's a spin-off of the quote "Begin with the end in mind." Know where you are GOING - it's about forward, and pushing on some more!
