oh Donna I am so sorry! I myself am an ex smoker, all I can say is I can't imagine going through what I have, and lighting up. I quit smoking when I had pre-cancerous cells on my cervics and learned that smoking increase my chance of cervical cancer by 40%. But you know, my husband is a smoker and also chews you would think after what has happened to me, you would think he would at least try to quit. Not a chance! I am so sorry, I can only imagine as a caregiver how much betrayal you must feel.
