I was diagnosed with COPD in September 2012 and stopped smoking after 44 years in early November 2012! My COPD s moderate-severe and I have been through Pulmonary Rehabilitation and keep to my exercise regime. The only disappointing thing is I feel more out of breath now than when I smoked. Does this improve over time and if so any idea how long ? I am a young slim 58 who was quite active. By the way PR is blinking marvellous -a must for all COPD people . Any ideas?
