Hi, I smoked thirty roll-ups a day for thirty five years. Gave that up with an e-cig which I still use. I'm in Pulmonary Rehab twice a week which I find helpful so I've bought my own oximeter/pulse rate monitor and weights. I know that COPD is irreversible but muscles can be trained to use oxygen more efficiently.
Anybody else here undergoing PR and still using an e-cig?
