COLD TURKEY!!
It happened one day, and I never touched a single one in 3.5 years.
You'll have periods where you wouldn't even think about it, and periods where cravings will kill you.
Be strong, and always think about the amount of time that passed that you accomplished NOT smoking and think that
just by one cigarette - you erase all this time and you have to start from scratch.
It really helped me when I craved a cigarette to just stay focused. I always thought: "it's been 3 months... why ruin it now.."
Now after 3.5 years, the cravings are almost gone with the 'once in a blue moon' 5 seconds craving that quickly disappears.
You have will power and you can do it
It's seriously the best thing I have ever done for myself.
