I have found that as I have got older my alcohol intake has dropped without even trying. I go for a drink with a bunch of friends a couple of times a week and am now quite happy with no more than three pints, often just the two. My friends, apart from one who drives to the pub, have around five pints each and I used to get jokes about my reduced intake but now it is not even mentioned.
I like a beer, but enjoy the company, the laughs and the arguments more. It doesn't matter if my friends are more 'merry' than I am. None of them are idiots in drink.
At home I hardly ever drink, but oddly have a full drinks cabinet, for visitors. I could easily go teetotal but at the moment it's not important enough for me to do so.
