Certainly not addicted. I can sometimes smoke for a few days in a row, several times a day, and then go for over a week or two without touching it at all and not feeling any craving. Not using during those times requires no self control.
Its also about levels of activity. When I have an abundance of free time I naturally think more about smoking and the action follows. Otherwise my mind is occupied elsewhere. I also work out around 4-5 days a week and I don't like the grogginess that sometimes follows an evening of smoking a lot. So I got a reason to do it less and again I would be smoking more if its on a weekend in which I dont work out.
