I was very excited when I managed 8 days without a cigarette and began to prefer my electronic cigarette. However, this did not last as I woke up one morning and could not breathe. My doctor now is testing me for COPD and given me a ventalin inhaler. What I find so weird is that although I do suffer with chest infections every winter I have never experienced symptoms of COPD. I have stopped the e cig and I am now using nicotine replacement. I feel so miserable. I have been trying for twenty years to give up and the cost in both health and monetary terms is ridiculous. Why do I do it?
