i have wondered this myself, and depending on what day you ask me, i will present a convincing argument for either side. for me it doesn't matter I know I had some issues early on that contributed to my alcoholism, but I also have a body that is "alergic" to booze. it processes it differently than normal folks bodies do. the physical aspect is often forgotten.
if I was a fortunate son, born with a silver spoon,and I was outgoing and popular, as soon as I got drunk the results would be the same. it just may have taken me longer to get where I am at.
Even if I resolve all the problems in my life and get rid of all my character defects I am not safe from the drink because my body reacts differently. That's what makes me an alcoholic.
good topic, it made me think, thank you
