Good luck. I had a heart attack 5 minutes after I put out my third morning smoke and now walk around with 4 stents. 14 years later, if I feel the urge when I smell the aroma of a freshly lit cig, I remember being on the table with tubes running into both legs, dye being injected, balloons being inflated while placing the stents and the click, click, click of the aortic boost pump keeping me alive. Somehow the urge passes.
