Quitting drinking was a picnic compared to smoking.
Yes, I haven't quit smoking. Of course, my dad dies of cirrohsis after drinking for 35-40 years, and quitting for 10 or so. Your lungs may heal after a while, but the damage to the liver from drinking is permanent. It wasn't pretty either.
Have sinus surgury, you won't feel like smoking for at least a week because you'll be feeling so horrible. After a week the stuff might be out of you (physically at least).
Unfortunately I resumed after that, because I still enjoy it very much. Life is full of risks, we have the freedom to make our own informed choices. Living and driving here in LA probably has a higher morbitity rate than smoking anyway!
