Just quit! Don't buy another one. Don't stick one in your mouth. It's just a habit. That is, unless you find yourself getting up in the middle of the night for a quick fix. If you can sleep for 6-8 hours without a smoke, then why don't you go that long during the day without one? Habit.
I agree, my Dad smoked for over 35 years and simply quit 25-30 years ago, and quit cold-turkey. He gained about 10-15 pounds (ate too much for a few months, due to the need to have something to do), but then lost the weight after 1 year.
Not saying it was easy, he would be the first to say it was not.
