I was 15 when I had my first cigeratte and that triggered my whole life . I am now 37and have been trying to quit. I have tried Chantix but it made me so drowsy that I couldnt take it. Now Im back to the drawing board. Smoking has caused me to have a few issues shortness of breath, chest pains,and messes with my acid reflux.Never knew stopping smoking would be so hard. To me its like a bad habit.
