Some people can really contain their habit. A guy that I sometimes do tree work with, has his drinks after dinner, goes to bed at eight, then gets up two hours later to have his glass full again. Every day like that for years and years. A cultural thing. I know other guys too that have to drink every night, but it doesn't seem to affect their lives in a negative way. Maybe their livers? They don't throw you in the tank for being drunk on the street either, and if so incapacitated that your safety is impaired, the cops will assist you in getting to your destination. or at least to a temporary sobering up location.
It's very easy to get drunk if you want to, aided by all the cool places that are around and at your service in that regard. Some are right next door to each other.
