This is really strange to me . I quit smoking on Jan 26th, 2018 due to the flu and the pain it brought. I literally thought I would die. My back hurt and my ribs hurt from coughing and I sat up due to wheezing to even sleep for 6 days. I then discovered I had emphysema , with minimal damage. I am now on Chantix week two and it has made so passive. I lack craving of nicotine gum that I was using so that works. The Chantix makes me so passive so far that I feel it is okay to smoke and have smoked a pack last week. This is irritating. I don't see my Doctor for three months so I am not sure about all this but I know I can do it.
