There is a huge percentage of the population that don't drink for varying reasons, mostly they make the sane, rational choice that it doesn't agree with them...the first time i got in trouble through drinking, if i had been a sane, mature adult, i would have not drank again...so comparisons to people that are of a sound mind are absolutely useless for anyone who has promised themselves not to drink again and broken that promise to themselves even if this has occurred only a few times in their lifetimes...
