Tips to quit!

I need help not to smoke! (Yes, ladies, I've talked to my doctor about it!) I have been smoking since I was 12, so it's been about 10 years or so now. I'm ready to quit! It's so expensive, and it takes up a lot of my time and money. Anyone have any tips or tricks they used to quit, or at least stop smoking so much?

(Vaping is not an option btw! It costs just as much and takes up just as much time! I'm looking for ways to sort of keep my mind off of cigarettes, not get into a new habit!)
