Congratulations Geoff. I was a heavy smoker and had a high stress job and at it's worst hit the three pack a day level. I knew it would eventually affect my health so quit cold turkey. I was determined (This time) to prove that I was more stubborn and powerful than those cigarettes. It has now been over 35 years. I had some recent medical problems and after numerous tests, the doctors said that my past smoking had not caused me any problems or damage. I am one of the lucky ones. I have a buddy who has COPD and he still "Can't" quit smoking. I will also say that it gets easier every day, so stick with it Geoff- show that YOU are the boss.
