Congratulations on making a tremendously good choice!
I started smoking back in 2001, in the army, and have been smoking on and off for about 10 years after that.
You write that it is going to be difficult for you, it may be true but remember that it is mostly your own attitude that lays the foundation of how you are going to feel about the matter. I would recommend you get into meditation and through that change your behavior - because that’s what it’s all about actually, breaking a habit.
Good luck and the future smoke free you will thank you for doing this :)
