I started smoking cigarette when I was just turning 17. Initially it was because "the cool kids" do it. Then I would do it to find interesting conversations with people (which I did). This went on for about a year until I accepted that I smoke.
Later on in life, I also picked up weed; and even later on, coffee. Life was good, at least for a good while, before the accumulating anxiety creeped up on me. At this point, I was smoking between half to one pack a day.
Finally, I decided to just quit cigarette. It didn't exactly take much effort to go against the craving (the weed helps, I guess). The hardest part was the lethargic feeling. Nothing I couldn't handle, tho. Cocaine withdrawal was way worse. Still, I needed for cups of coffee accompanied by a fat joint for each cup just tp get thru each day.
After a week or two, I was able to taper down on the coffee and the weed. All was good then. Within the first few years, I would dream about smoking cigarettes every now and then, but I never have gotten some real craving or anything.
This past couple of years, I was able to smoke cigarette socially when I meet with old friends and then live without any with no craving at all. The last cigarette I smoked was earlier this year.
