In my opinion this song deals with what happens when a person is an alcoholic and how their sickness affects their life and even the life of others. The song deals with such issues as low self esteem, denial, and dependency on alcohol. We can tell that the "narrator" of this song is the one involved because of line 3 when he says "alcohol, alternative to feeling like yourself." This means that the person drinks so they're not themselves which shows they are unhappy with themselves and life. Many people drink for this reason.
We learn this person has an addiction in line 1, "alcohol, my permanent accessory." This means he needs alcohol. He uses alcohol to loosen up but he usually ends up doing something stupid. This is shown in lines 28-30 which says "would you please ignore that you found me on the floor trying on your camisole?"
This song is really good not only because I like the band or how the song sounds but because it deals a lot with health. Health just isn't physical anymore, it also includes our mental and social health as well. This song deals with all forms of health. Some people may think this song promotes substance abuse but when you sit down and think about it it really is the opposite. It tells what can happen when a person abuses alcohol.
