I too quit cold turkey. Just got into my mind to stop so I did. Never cough up anything thankfully. But I know it fucked up my skin, and had a doctor tell me that my lungs had little holes in them and I should have ephesima which I don’t again thankfully. I am also glad I quit because my ex wife didn’t and she suffers from COPD and looks twenty yesrs older then me, even though she four years younger then me. And she still smokes.

For me 10 years smoke free next year.
