For me it wasn't that I wanted to quit, really. After 30 years smoking and a PAD for 25 of those, I finally started to feel the effects of smoking. Started with coughing in the morning, then during the day. Still, not too bad. About 5 years ago I got a really bad cold/flu that turned into asthmatic bronchitis. Got my meds and an inhaler, and still smoked for another 5 years. After that bout of asthma the breathing problems never really went away. My wheezing at night got so bad that it would wake me up to clear my chest. Eventually I couldn't sleep on my side or stomach because my lungs would crackle and I would start choking. More coughing. Still didn't quit. Didn't really want to, or maybe I was afraid that I might not be able to, so I never tried. But I was TIRED of feeling like crap all the time.
I picked up a disposable along with some smokes one day, thinking I could cut down almost half of my smoking if I vaped in my car on the way to and from work.
Tried, it, liked it OK but not enough to stop altogether. But I saw the potential and found ECF. That got me inspired to try a "real" e-cig, and 24 hours after I bought one I didn't even think about smoking. Before that, the longest I had ever gone without smoking was 4 hours (except while sleeping), and even that was hell. I've fallen off the vaping wagon a couple of times, but not for long. Because now I can BREATHE, I don't cough, and I sleep like a baby now. I know I won't go back to smoking full time, even if I fall off the wagon again. I just feel too much better vaping to want to go back there again.
