I am 8 weeks pre-op and I'm already experiencing some of these wonderful changes. I had to quit smoking before my surgeon would agree to operate. He is requiring 3 nicotine test at 30 day intervals to prove I quit smoking. I've been nicotine free since 8/12/14 now!! Just like food, my life revolved around smoking. All the little things we do every day (like getting in a car or drinking morning coffee), I associated with smoking. The first couple weeks were really tough because of that. I had to constantly remind myself I was a non-smoker now. I couldn't even think of it as "I quit smoking". That implied I could start back. No, I have to think of it as "I'm a nonsmoker". No chance I'm letting that habit get a hold of me again. But gradually, as the weeks past (just started week 7), the habits and the way I thought about them changed as well. I no longer have to remind myself I don't smoke when I get into a vehicle or pour myself a cup of coffee. It's just the way life is now, I'm a non-smoker. Don't get me wrong, the battle isn't over yet. I still get cravings occasionally, and I do have to remind myself at those times. But in general, my life no longer revolves around getting in a cigarette. I know if I can beat that demon, I'm going to be successful at my WLS too. Just remember, you're not "dieting", you're living a healthy lifestyle and that's just the way it is, it's not temporary.
