Earlier quoted context omitted.
Maybe you are confusing the word "guideline" here with actual recommendation. You are not suppose to be drinking 14 units per week. You are not suppose to even be drinking every week. In any case you still as much light wine as you can reasonably consume. 2 bottles of liquor and half a bottle of fortified wine on top of your beer. If you consume even that much everyone month I'd be calling you an alcoholic.
Someone drinking an average of 6x 33ml cans of 4.3% beer a week would not be called an alcoholic in any normal conversation. That's 4.4 litres of alcohol a year - less than half the US intake (9.8l), less than Norway (7.5l) and would fit well in the bottom half of countries by alcohol intake. The ability to drink other things (scotch, wine, etc) is irrelevant if you only drink beer.
Maybe it is just the lives I've seen ruined by alcohol that as made me grumpy about alcohol consumpsion, but I would be concerned if someone is drinking enough to have a hangover every weekend.
