After watching my beloved momma die of lung cancer, I knew I would be next. I smoked 42 years and less than a year later, I was able, with the help of Almighty God to put cigarettes behind me. It's been 38 months and I was interested in the conditition of my lungs. I recently had to get an x-ray pre-op of my lungs and I was relieved they found nothing out of the ordinary. Praise God! I quit because I was coughing all the time, wheezing everytime I layed down, couldn't smoke anywhere in public, but mainly because of health reasons. My 02 sats runs genuinely at 98 percent. Regardless, up to this point, I am blessed.
