Good luck with that, CD. I don't know how tough it is from personal experience. My mother quit before I was born and admitted that even 30 years later she would have dreams where she was smoking and would wake up with cravings. My twin sister suffers from COPD that she thinks was caused by smoking, and during times of stress she is tempted to buy a pack. It's difficult but the benefits are worth it.
"Well, evolution is a theory. It is also a fact. And facts and theories are different things, not rungs in a hierarchy of increasing certainty. Facts are the world's data. Theories are structures of ideas that explain and interpret facts. Facts don't go away when scientists debate rival theories to explain them. Einstein's theory of gravitation replaced Newton's in this century, but apples didn't suspend themselves in midair, pending the outcome. And humans evolved from ape- like ancestors whether they did so by Darwin's proposed mechanism or by some other yet to be discovered."
