I am very fortunate in that I never managed to smoke - not for the want of trying because it was fashionable in my youth. I just couldn't do it without choking. All my family smoked. My father died of lung cancer at 59, my sister died of heart disease caused by smoking, at 46. I am indeed lucky. However, my husband smoked heavily and gave up a couple of times in his life, the last time for 30 years. He was like a bear with a sore head while he was in the process of giving up but reckoned the only way was will power and cold turkey. Very difficult. I hope you manage to stop craft, lung cancer is not pleasant either to suffer or for those nearest and dearest to watch.
