Really? One person drinking five glasses of wine over lunch seems normal to you?
Looking at the UK guidelines, a bottle of wine is generally ten units and they suggest under fourteen units a week spread out over three or more days. So that "social lunch" seems to be binge drinking in the UK too.
Your government would still consider it drinking in excess of their guidelines, which is binge drinking. One of your other comments suggests you know this, as you're aware that it's not something you should do everyday.
Yes, I agree that is what the government say. I'm just telling you what happens in reality.
And I don't do it every day because I am old and hangovers are now a multi-day affair. In my younger days I could have easily done Friday, Saturday and possibly Sunday.
