My grandmother died of COPD last October. She had smoked for 65 years, only giving up 6 years ago after being hospitalised many times with chest infections-she actually lived a lot longer than we had all expected her to but the last 18 months of her life were spent on an oxygen cylinder up to 22 hours a day. She hated it and used to say how helpless she felt and how much of a burden she thought she was to her family. My brother gave up smoking 2 years ago with the help of the Alan Carr book and hasn't looked back since-he doesn't even crave one when he is around friends that smoke now. I am sorry to hear about your husband, Belle Du Jour.
