I remember only to well worrying about Marks cough that was happening more often especially at night so he finally made up his mind to quit, he was still working away alot at the time plus he worked with several smokers but he was determined! He also saw his Dr and had chest xrays plus a CT scan when he saw his Dr again and found out he had mild copd he'd already had over a month quit!I figured I was fine so I kept on smoking, outside of course which we'd been doing for yrs anyway I had a Dr's appointment that June the Dr listened to my chest and sent me for a breathing test which showed mild copd! Anyway to make a long story shorter I I found this site on line and read everything I could which strengthened my resolve to quit and stay quit WHEW it sure as hell wasn't easy BUT it sure as hell was AND is worth it to be Free! As difficult as quitting smoking AND or Vaping or dipping is thankfully with commitment AND perseverance it's absolutely doable AND totally worth it to be Free!
