This weekend is my two year anniversary of quiting smoking. For all of you thinking of quiting, do it. And stick with it. I used Chantix, and for all the negative press, it worked well for me (and my roommate). If you can go cold-turkey, so be it. The important thing to know is that there are people to help support you through something like this. The manifestations of smoking are insidious. Although diagnosed with emphysema years ago, a little cough wasn't going to stop me from enjoying "just one more smoke." Even 'clinical death', that is cardiac and pulmonary arrest during surgery, wasn't enough to make me quit. It wasn't until I woke up one Saturday knowing that was the day I was going to die from coughing, that I finally quit. I won't lie and say it's been easy. But, if I were still smoking, no doubt I'd be dead by now. I'm waiting for another lung biopsy to see if the new mass in my lung is cancer or not. I can't walk faster than 3.0 mph on the treadmill no matter how much I will myself to breathe deeper. If you can quit, now is a good time. For me, one day at a time. Be well and breathe deep.
