I started getting ready to
stop smoking about 5yrs ago. I decided not to smoke in my car anymore. I suffer from anxiety, so I'm never away from the house for more than 2hrs max and I figured I could at LEAST go without a cigarette that long. At the time, I felt like this alone was an enormous accomplishment and it helped me to start thinking like a non-smoker,
I had been a smoker for 33yrs before I quit last July.
