"Just keep passing the open window!" That's the only advice I can give. I just know how much more money I have now that I stopped. I was smoking 3-4 cartons a month...which REALLY added up. I figue I've got about $150-$200 more a month in the budget. That's a big incentive.
That stated, I still smell cigarette smoke sometimes & it "tickles my nose."

It's only been three years since I stopped, & I still find myself smoking in my dreams sometimes. My urges aren't as great now, but I still have momentary urges sometimes.
Freedom is a big issue with me, too. I can go out with my girlfriend & not have to think, "How long until this damned movie is over?" because I'm jonesing for nicotine. It was the same in other situations...I always had to plan an exit route every two-three hours, or go out in sub-zero weather to smoke when at friends' or relatives' houses. Looking back, that's crazy stuff!
I'm free now.
I might have mentioned it before, but when I was first trying to quit I'd wear a rubberband around my wrist. I'd snap it any time I startedf to get the urge. Something about that distracted me.
Anyways, I'm glad you're doing so well! I'm especially impressed with how well you're doing with the stress in your life. Keep it up, kiddo!
