Congratulations. This is a very smart move, one I made several years ago and have never regreted.
You may not think about it until you quit, but isn't it amazing how many sick floks you see still puffing on them. I watched a fellow at the hospital a while back, he was on oxygen, in a wheel chair, yet he still managed to roll himself out to the parking lot in 100 degree weather and light up. He was lighting one off another for about thirty minutes or so. I bet the nurses thought he smelled like crap when he returned to his ward.
I have witnessed firsthand the pain and suffering a person goes through as a result of smoking, my wife has COPD, she has to have oxygen to sleep, needs a breathing treatment several times a day, and her physical activity is very limited, she can't walk without stopping to rest it ain''t pretty and something you wouldn't wish on anyone, but I couldn't convince her to quit smoking when I did many years ago, she continued to cough and lite up, today she wishes she had taken my advice.
