Quitting smoking was an easy resolve for me to make at the time.
I was broke.
I coughed shit up left and right.
I woke up with asthma attacks at night.
As it turns out, Primatene Mist would give me migraines.
I know people that have smoked twice as long, and twice as much, and were effected much less than myself. It was the best decision I ever made, and maybe the hardest. I had to quit drinking for three months when I quit smoking, because they go hand in hand.
I also know this......My body doesn't care where the nicotine comes from. If I smoke one cigarette, have a chew, use the patch or gum, or take in any nicotine, then it's like I never really quit. It was all about the physical addiction for me, more than the having something in your hand thing that other people talk about.
Three years, and I'm happy. I smoked and chewed for at least 7, although the chewing was during the last year, while working. I smoked after work.
