Weekend Warrior

So I took Zyban and kicked the habit. Then broke up with my boyfriend and picked it back up, but only on the weekends. I now have a personal trainer and I am really starting to get in shape, but when the weekends come I am a virtual chimney. And I have a weak heart to boot. So why do I still smoke, even if just on the weekends? An association habit. Let me explain: There is a little disclaimer on the side of all alcoholic beverages that I recently discovered. It says: "If you consume this beverage you must simultaneously smoke an entire pack of cigarettes." I know everyone can relate. But at what point do we take control of our health and our future and just say f**k this? Somebody please tell me.
