Well, it seems the deeper I dig, the more complex it has become. My golf coach is always saying I over think things. My philosophy has always been "knowing the why makes the how so much easier". I'm beginning to see thing more from his perspective. When I see people around me who have quit for good, the common denominator seems to be simplicity. The Nike approach. They decided to quit for whatever reason (health, finances, nagging spouse) & just stopped. Oh, how I envy those poor simplistic fools!
I still feel strongly that the key to relapsing several months into a quit lies in comparative levels of brain chemicals & those neural pathways reinforced over years of repeating a behaviour 20 or so times a day. The strategies to developing new neural pathways are in chapter 5 of Loretta Breuning's book. I've resisted jumping ahead to solutions so I don't miss anything vital. Chapter 2 covers the "unhappy" chemical cortisol & I suspect elevated levels of cortisol may have a greater role to play in my situation than the absence of stimuli for the "happy chemicals".
