I gained a few pounds but weight gain is reversible, while emphysema is not.

I did some serious soul-searching in the first couple months because I’d found that, after smoking since I was twelve, my whole image and ideas about Coolness were all tangled up with smoking and I had to find a way to rework that. But that was an awesome residual effect. (and it helps with another one of my Things: Stop Trying To Be Cool)
