HEYYYYY!! Good on ya, brother!! You just extended your life by many years! I smoked for 13 years and finally quit 16 years ago. Sure, I'll still have a cigar on campouts a few times a year, but that's the extent of it.
I'll tell ya: it'll really suck for about a year. Then, the smell of cigarette smoke (especially in peoples' clothes) will NAUSEATE you. It's awful, and I'm embarrassed to know I walked around smelling like that.
Proud of ya, Chief. Keep on it.
