Well, I checked off the middle one because it is not rare at all for me to smoke simply because my neck is acting up, or because I can't sleep... Though typically thats not why I smoke. I hear you on being in pain though. I got some wicked knees, elbows, shoulders, and now my neck is toasted as well... Though I'm getting my elbows and shoulders back into finally (light push-up type work outs a couple times a week)
