Eastern European here, but I spent most of my adult life in the UK. Almost every person I know drinks a few beers or shots a day. 2-3 on a normal, uneventful day, and a about 5-8 drinks when meeting up with family/friends etc, and 10-20+ drinks on a night out.

None of them show physical symptoms yet, all highly functioning people, but I suspect that is mostly due to their youth (20-40).

I personally went teetotaler about a year ago. Drinking is loads of fun and I miss it, but I appreciate a steady mood now way more than the ups and downs of alcohol induced euphoria, then potential anxiety etc.
