Supermoms don't smoke...period. Smoking does nothing for you but cost money and cause unnecessary health problems, even if it's as small a problem as making you too tired to get in soe good exercise. If you are doing it around your kids, don't even get me started on the bad behavior-modeling you're doing, and the health problems you are knowingly exposing them too...maybe even against their will. Not to mention, try as you might to cover it up with perfume (generally, the cheap stuff, it seems), you still smell like an ashtray, and everytime you flick a butt out your window or onto the sidewalk, you are a litterer, too. It is not sexy or sophisticated...it is a disgusting habit that has nothing but a negative impact on so many aspects of your life...you should know better!
And, no, I don't care to debate the finer points of why you're still smoking...in case you have missed all the reports on the pitfalls of this habit, there are no finer points to it. So, consider quitting NOW! Smoking is not something you need in your life...no ifs, ands, or...oh geez, I can't believe I'm going to say it...butts about it!
