I know men who refuse to include a non-alcoholic drink in their round.I have had struggles with alcohol myself, and after a particularly bad breakup it became an issue so I gave up for a few months to get myself back on track, I just told friends /colleagues etc it was a health kick, I was shocked at work events especially when people were trying to force me to drink/pretending things were just a tonic water not a g and t etc, I would never dream of doing anything similar
In Ireland, a woman not taking a drink is regarded as a pregnancy announcement. Even a reason given like "I'm on antibiotics" is argued - "but you're grand on amoxillin!" I like a drink, but this really appals me. I think it's to do with the drinkers being afraid that their behaviour is being called into question, and worse, that it will be remembered with clarity and judgement by the non-drinker the next day. Anything but taking a look at themselves.
