A pack of cigarettes and around 5 small cigars a day. It took me a few months: I started to wait longer in the morning before getting one. It's a drug but also a habit of having something between our fingers and our lips. When you want to smoke, before lighting keep it for a while between your fingers or your lips; at the beginning it will be 3 minutes, later 10 minutes, etc... At the end of the day, willpower and all these tricks will reduce your consumption.
One day your first cigarette will be after lunch; you'll smoke only 4 or 5 a day... When you arrive at one or two a day, stop buying a pack because without one, it's easier to resist. At this point, ask people around for a cigarette; some do not like it, I used to pay for my cigarette!
Avoid drinking too much coffee, it goes so well with cigarettes... I remember reading that licorice is used in the production of cigarettes and, as I have seen others doing it before, during those months I chew licorice sticks. It really helps!
When you arrive at your single cigarette/day and you finally decide to quit, the first 2-3 weeks are tough but think about your health and how stupid smoking is...
Start now!
