I quit smoking late Dec., 2011. I wish I had quit sooner. I have been diagnosed with moderately severe COPD this year. COPD is chronic lung disease with no cure, only medications to slow down the lung deterioration. Most people diagnosed with COPD were or are smokers. The best thing you can do for yourself is quit smoking! I used the forums to help me with my cravings while I was quitting & found it really helped. Please keep quitting!
