There is one aspect of alcohol consumption that’s not mentioned here.
If, say, you’re like Andy, brought up in a pub style and mentality (you never did say why your parents / guardians thought this was a suitable place for your formative years btw) , then food is unlikely to be consumed at the same time as the drink, as say in a restaurant or with the continental style of eating and drinking.
What then, the next morning?
I think you will find there’s a paradigm shift in societies view on drug abuse (alcohol) once you choose to get behind the wheel of a car / van / lorry after consuming any alcohol (whether you feel it’s OK or not, whether your “mates” do, or do not), when it is no longer a private, personal matter.
Similarly, the law is not tolerant of drunk drivers; & nor are we.
Just a thought.
Also, I've rented out rooms for many years and seen too many men who thought they didn't have any problems with alcohol (3 pints a night, tops!) and then drove to work, 5 days a week.
