Three Reasons Lyrics

To me, it's obvious that the song is about someone who uses alcohol irresponsibly and to excuse his/her actions. I don't see why this song necessarily has anything to do with straight edge. I'm well aware that Davey is, but I drink moderately and know drinkers who invoke with me the same type of distaste that Davey has for whoever inspired this song.
