Now is the time to quit. Take this advice from someone who smoked and had to have 5-way-bypass surgery 5 years ago. I have never smoked a cigarette since, but unfortunately I gained weight. Go figure. I'm just giving you a bad time. I recall everytime I was stressed I smoked, but I paid the price big time. Try using the patch. I had to go cold turkey but I was in so much pain from having my chest cracked open a cigarette was the last thing on my mind. I think my surgery is a few mo. away, but I wanted to meet some people on here and know what the surgery was like and what to expect. Good Luck.
