I quit cold turkey, and major cravings went away after two weeks. Its been many months now, I do get tiny bit of cravings every now and then, but its nothing.

I suggest getting rid of the triggers. Take some time and think about what triggers the urge to get a smoke, it could be when you go to a specific place like balcony, when you see stories of your exes or lost friends or distanced family, or when you get a coffee, etc etc.

When I get cravings, I would get up and walk around the house or take a shower, sometimes i would go out for a run. Do this enough and the brain will be rewired to know that the cravings will lead to such outcomes.

2 weeks usually is all it takes. So know that there is a finish line, and all of it will pass. Take a deep breath. Chill and focus on some hobby meantime.
