I smoked 2, 3, occasionally 4 packs of cigarettes a day for 40 years. I quit in 1999.
Today I have COPD and attribute it to smoking so heavily for all those years. COPD is a progressive disease meaning it will probably kill me eventually.
I you don’t smoke today, please don’t start. If you smoke today please strongly consider quitting. I quit a number of times, trying various schemes to quit. I finally found the way to quit for me. Just quit, cold turkey. The first 3-4 days will be hell. After that it gets easier and easier.
I only smoked for 4 years (while I was in the USAF in the late 60s), and looking back when I got out, quitting cigs was THE most difficult task I've ever successfully accomplished.
I was lucky, I started college in pre-med, and I was clued into just what cigs did to very nice people. Fear is such an excellent motivator.
I'm glad that you were able to kick the addiction, and I'll wager that your story will help others.
