When I retired from the Navy (Submarine Service) in '82, I went cold turkey from 3 packs of Marlboro a day. A year or so later, at a party, I was blurbing on about how easy it was to quit smoking......."Never bothered me a bit.....blah, blah". My wife gently reminded me "Bullshit. You were the meanest SOB on earth for 6 months".
