Thanks, Carolyn, Izzy & Hops...(am I leaving anyone out? I apologize.)
Well - I break this down like this:
I need a plan that includes goals & rewards. I need a strategy - the actual how-tos. And I need a whole truckload of techniques & replacements!

Hops' point about the physical/mental addiction is now the center of my strategy. It was an excellent reminder Hops - thank you very much! Smoking energizes/activates L-brain activity and suppresses R-brain, for me... and this was another way of validating (L-brain) through invalidating (R-brain). As a general way of thinking about the difference, L-brain is my process skills, intellectual/mental thinking. R-brain is more emotional and physical sensation... day dreamy, more creative, still "thinking" but with intuition and emotion, rather than logic... Just needed to define this for myself, before backing up and laying it all out.
The plan is this:Beginning this morning, whenever I pick up a cigarette - I ask myself to decide if I really, really WANT it and why. And then, while smoking it (doing absolutely nothing else) consciously testing myself to see if it fulfilled that want or was just a fix for the addiction. I have designated smoke-free zones... haven't smoked indoors in years... have begun including my jeep... and today am adding smoke-free TIME zones - removing the smokes that are simply habit, associated with breaks, etc. Limits start tomorrow with half a pack. Since Monday is the first no-smoke day, that adds an urgency to the stepping down. I've been tracking the number (and time/place) for years now.
Goals are: positive validation of self w/o invalidation, better breathing to enable increased strength & stamina - longer life; enabling me to progress to another level of tai chi work; and actively engaging in all the family relationships that give back to me (while letting the others that don't give back, go...along with SMOKING). OH! and another big one: intention/attention to food - quality, quantity, and the act of eating. That's a topic in and of itself... maybe later. But it's useful to give me something other than the quit to focus on, and it helps me deal with the weight gain issue that I'd rather avoid, if possible.
The Strategy: Letting GOI recognize that letting go isn't FORCING, isn't draconian, isn't merciless, doesn't really have rules. Absolutely NOT allowed to kick myself for slips - but not allowed to give up a quit because of 1 smoke EITHER. (Izzy's approach is an example of what for me, would be an big improvement... but Twiggy & I want smoking gone completely... so that might just be another "threshold" I reach on the way...).
Letting GO is actually a "lightening of the load" while moving toward something new. The journey on a 2 lane road. I have to allow it to be what it is - be open to curves in the process; be ready to accept them.
Every time I quit - there is a convenient emotional uproar to justify or become an excuse for more procrastination or a slip. Sometimes, it's just a normal thing that I let get blown all out of emotional proportion. I know I will face this again - and I'll have to distinguish real situations from excuses and deal with them differently. It was really ugly with hubby, the last time I tried to quit - I swear, every single bad dysfunctional communication habit I learned from my mom simply took over and made both of us miserable. Sometimes it's work stuff - sometimes it appears out of thin air.
So the strategy is to start the quit Monday morning - at home, in the morning - these are the most "fix"/addicted smokes, with my coffee. Going to limit the coffee to 1 cup in bed and 1 cup in my "chair" (where I've worked with Twiggy all along) (These are No smoking zones). Not smoking has made me hyper, in the past. I have a list of things to do INSTEAD of smoking in the morning.
I am already adjusting - shifting - postponing my work smokes to odd times.... not my normal routine. I will have all kinds of replacement goodies for myself and have enlisted the support of co-workers (non smokers; some former) to simply put up with me, talk me down from emotional ledges and give me time away from the computer for these breaks. I'll be scheduling automatic reminders in my calendar to get up & go walk throughout the day - once a day a longer walk with a buddy in another building. Work is only 2 days next week - then I'll be at home... and hubby at work. I have several lists of tasks that I've procrastinated on, to work on. Inside tasks, if it's too hot (and of course, hot weather will discourage being outside in my old smoking spaces.) When I need to simply rest - sit & be - I'll be able to do so. When I need to work off restless energy, I can do that.
And I can direct a lot of attention to food... which will help take my mind of smoking!

Don't need another obsession, you know?
Chi gong will help balance any energy spikes/lulls... and the breathing part of those exercises will get me through cravings.
I have cinnamon toothpicks for oral, nervous stuff...
homeopathic pills to help reduce cravings...
my inhaler...
and I'll stock up this weekend on celery/carrots & hummus; tic tacs.
I'll start vitamin C and detox tea on Monday; I always drink my 8 glasses of water (or more) a day anyway... plus herbal tea....
and our bookstore carries lots of things, if I run out, to use as rewards. It's important that my rewards are things Twiggy wants; likes. There are daily rewards, weekly rewards, monthly rewards, etc. I'm also creating a can to add $3.50/day to, for each day I don't smoke. Haven't designated what the money is for yet - but since we go to the beach in October, I think it's going to involve crab, oysters or shrimp. Maybe a bathing suit - they'll be on sale then. Some of the rewards aren't material - they are designed to soothe and reward my emotional self...
In this prep phase, when I have a craving prompting me to smoke - I'm practicing my "full stop" exercise: deep breathing, grounding myself, eyes closed... just breathing and feeling just fine in my body WITHOUT getting up to smoke. I've febrezed anything that smells like smoke - including my jeep... there is only 1 ashtray... and 'coz I know I'm going to be around smokers, have been practicing not smoking with hubby - even with my own smokes around me. Just not smoking. It's not that difficult or a big deal.
And I'm an hour into my first smoke-free time zone; I can only have my next smoke after 4 pm. That's a start folks - there's MORE. These are the things I know work the best for me - I'm going to be relying heavily on chi gong & tai chi during the first phase of the quit, but yoga, walking - any physical activity that also refreshes the brain would work, too. I've found myself sneezing a lot in the morning - after re-affirming & journaling my prep to quit... guess my body's already trying to detox... expel the evil spirits...
I can tell from re-reading this: my r-brain is strengthening - typos galore; dyslexia even - odd grammatical patterns. Good thing I've been practicing tai chi with an active r-brain... it doesn't freak me out anymore; it's not a handicap - Twiggy & I know how to manage it. And I have a Nintendo DS game for R-L brain balance... that might help at work...on breaks.
