Wow, thanks to all three of you for all that great info. I know it's the purpose of this forum, but it still amazed me to log in and see three replies, all from perfect strangers just taking the time to help! It means a lot.
My mom is not at a CCC currently, but I would like her to at least get an opinion at one. Meanwhile, I know the quit-smoking thing is imperative. For the first time ever, I think she is actually open to giving it a try. I talked to her primary doc yesterday and he's going to try once again to get her in his smoking cessation program. In the end, of course, it's up to my mom and I can only support her. I'm hoping for the best.
Once again, thank you for taking time to share your knowledge and experience with me. All the best to you and your family members.
