I usually drink just a few units of alcohol per week.
It's about a week since I had the second half of a bottle of wine, which was several days after I'd drunk the first half. You'd probably have to go back another week or so to find when I last had a drink before that which, if I recall correctly, would have been a couple of cans of lager.
As indicated above, I tend to drink either beer or wine. I do like spirits but I rarely drink them. (I bought half a bottle of rum at Christmastime. I've still got two thirds of it left. It's much the same if I buy a bottle of whisky; it can last me a year or even longer).
I enjoy drinking alcohol most in a pub, where it's mainly for the social interaction but, even then, I don't go mad. I'll just have two or, at the very most, three pints of real ale. (In the months before the first lockdown, I was generally only going to a pub on Sunday evenings, to do a few crosswords with a couple of mates. As I had to drive to get there, I was only drinking Coke or coffee most of the evening but possibly finishing off the night with just half a pint of bitter).
In my younger days though I was drinking far more. For example, back in the 1980s I was probably consuming around 60 units of alcohol per week. Going further back, to my college days, the figure would have been even higher.
So, as all the foregoing should indicate, lockdown hasn't really affected me much as far as alcohol consumption is concerned.
