Smoked for 20 years from age 14-34. I was on 2 packs a day by the end, 3 packs if I was drinking. I was about to get married and a mate died. It made me think about my choices so I just gave up. It wasn't easy, I'd failed loads of times before, but I did it cold turkey. 12 years now and it's the best thing I ever did. I cut down on my drinking after that as drinking without smoking was never as good. I haven't drank in 4 years now.
Literally everything in my life is better without smoking. My health is better, my family aren't subjected to my poison, travelling is much more fun, work is much less stressful... I could go on.
I know very few smokers these days. Most have given up.
