I must admit I don't smoke, but I'm a lifetime asthmatic and have been around it my whole life because my dad is a 50 yr smoker - up until 2 yrs ago. You can do anything you set your mind to - I'm rooting for ya! My father just quit smoking 2 yrs ago cold turkey for the 8th time after 50 yrs of smoking - this time it's for good because he was diagnosed with type 2 diabetes. His trick this time was he reluctantly gave up coffee too because for him the two go hand in hand. Now he just focusses on hunting and fishing more and making it to the gym. My mother in-law just died from lung cancer Dec, 26th, 2010. I saw her die and gasp her last breath after being over at her house for a week straight seeing her labored raspy breathing. That was the most dramatic thing I've ever witnessed. She likely got cancer from 2nd-hand smoke of her husband who smoked like a chimney - she never smoked at all in her life, but my wife tells me stories of driving in the car with her dad and he would be smoking away with all of the windows up. So remember you're not only helping yourself, but also your loved ones too, who need their own health and also would hate to see you go too early!
You can do it!
Every time you really want one, just go outside, get in your Mopar and do a burnout. Just joking - had to throw the car in there somehow.
