Cold Turkey. Yes. That's exactly what I did, in 2014, after 20 years of smoking, and it works. You must decide, absolutely, NEVER AGAIN. Not even a brush close to smoking again. After a week, it was easier. After a month, it was a new way of life, and a much better one. You'll see.

Cold turkey worked for me. Took me 4 attempts. I wasn't hard on myself for failure, I noted what happened (emotional trauma, stress, alcohol) and prepared myself for the next attempt.

I wanted to quit, so when I relapsed it's not because I wanted to smoke but because those little cancer stick bastards were trying hardest to kill me. But if they were going to be tough, I could be tougher. I found it easier when I could see the cigs as my enemy.

Honestly, this is it. You have to want it, and you just have to do it. You'll feel "sick" for a while but you just have to muscle that out.

I know it's easier said than done, but it really is that simple. Just stop.

I did the same and can confirm it worked. First two weeks will be the worst, then it'll be easier. Just be stuborn and aware that your will is stronger then a habit and that it doesn't have power over you. The urge to smoke will remain but at that point you need to be aware that even if you're convinced you want a smoke, it will taste really terrible when you actually do it and you will regret you broke your streak of non-smoking days.

This is also the only thing that worked for me
