Done and good luck to her. Tough stuff.
My wife quit when we got married. Cold turkey. She finished her pack and never bought anymore. I wish I could bottle whatever resolve she had. She just mentioned yesterday, after talking to a smoker, that she never really knew what she had smelled like when she smoked and that she was surprised no one ever said something.
Even after debilitating surgery to remove smoking-related bladder cancer, her father still can't quit and I think he's just given up now.
