Never smoked thankfully. I substantially gave up processed food, carbs, sugar, etc. a year and a half ago and dropped 35#, more to go. That said, my wife and I were up at 4:30 yesterday. We had not had dinner the day before. She founds a can of Mary Kitchen roast beef hash in the pantry so down it went. About the same time of eating better I gave up chewing my nails. Now I am amazed at how fast they actually grow. Cutting back on booze very recently and working to quit fully in the next month or so.
