- I agree with some PPs who note that a lot of heavier drinkers seem to mockingly disbelieve those who say that they drink far more moderately, or rarely.
I think this is partly as a defence mechanism - no-one wants to be an outlier or to feel judged - but I think the main reason that heavier drinkers don't believe moderate or rare drinkers is that big-drinking or binge-drinking groups tend to self-select:
Firstly, because one's attitude to alcohol and the acceptability of regular, excessive or problem drinking has been informed by their exposer to familial attitudes to alcohol as well as those of one's immediate geographical and social peers.
Secondly, because those people who don't want to write themselves off every weekend, or find the insistance upon pouring alcohol into every single social occasion tedious, will tend to avoid investing in relationships with those who do. Not everyone, and not all the time, but definitely as an overarching pattern.
E.g. My partner's friends, who mostly all went to the same two high schools and lived in the same or adjacent suburbs, all consider binge-drinking to be normal. It is unremarkable for them to drink 10-30 drinks in one sitting. I grew up with an extended family with many problem drinkers. When I first started seeing him, I hung out with them a few times as you do.
I quickly grew tired of the slurred-speech, the stupid roundabout conversations about nothing and their unpredictable, irresponsible, reckless, anti-social behaviour. So now I see them once every two years or so, if that. There was more to it than that, but it was a big part of it.
...Other lifelong friends dropped out of this group both before and after I showed up, presumably for the same reason.
- To support their bias, a huge number of PP in this thread have appealed to the reality that people tend to underestimate the amount they drink, or minimise/outright lie about their intake.
And that's true - but by and large, the people that do that are going to be the heavy drinkers:
...Someone who has only 1 unit per month is just not going to feel the same pressure to minimise to '1 unit every 2 months' when self reporting, as someone who has 20-40 units a week might feel to self-report at '15 units a week'.
Similarly, a moderate/rare drinkers' likelihood of accidental underestimation is significantly lower on the face of it.
- Well done OP on proactively taking such significant positive steps - it's a huge lifestyle change and that's not an easy thing to do.
To answer your question - I consider regularly consuming 20 units a week to be a lot.
I don't think it's unreasonable over a holiday period, or a month with a lot of birthdays and events.
It is a rare month that I would have more than 2 or 3 units of alcohol. Many months I'd have none.
