I don't drink either. I'm an alcoholic, now sober with the help of Alcoholics Anonymous, a good discipline and a healthy way of living.
I've been the ugliest embodiement of what alcohol do to human mind and body, and even being drunk on some occasion (without being a pathologic drinker) is being stupid, looking ridiculous and aving impair judgement.
I might be not really objective, but I totally approve the total abstinence of alcohol and other drugs.
