Great job! I quit 16 years ago and have never regretted it. I tried to quit several times and, yes, it did get easier each time. I started by eliminating cigarettes gradually before my quit date. I quit smoking in my car, then quit smoking in the house and smoking only in the garage, then I quit smoking in the garage and went outside. This method worked for me by gradually cutting out my favorite times to smoke, like first thing in the morning with my coffee or after a meal. I avoided alcohol for a while, too, since smoking and drinking just went together naturally.
Good luck.
