It's great to hear so many are quitting smoking.
I quit smoking, I think around May or June of 2013. I guess I used AVRT. I started with whining and whining about it with soberlicious through pm's and, with her encouragement and responses I finally just said "the hell with it, I'm done for good" and much like drinking, that was that.
My main concern (or was it my beast's main concern) was weight gain but as I eat mostly paleo/primal (started April?), I had no problem with weight gain. I guess I got somewhat crabby at points but spend most of my time alone so nobody suffered adversely from my quitting except maybe my dog who had his little legs worn down to near nubs as I walked him near to death
Anyway, I'm just glad to hear so many are addressing their smoking and desire to quit. The health benefits I've experienced are fantastic.
