I was trying to make a very serious point without lecturing anyone, but it seems it was misinterpreted.
Drinking too much is a symptom, not a cause. Saying "I'll be good! I'll stop for X period" does not address the cause. It is exactly akin to binge dieting. I doubt if it will do any good in the long term, What is needed is to address the long term problem, & that means long term behaviour changes, not complete abstinence for short periods.
FYI, there were years when I drank just about every day, at levels which I think would have done terrible things to my health if I'd kept it up until now. Maybe I wouldn't even have lasted this long if I hadn't changed my behaviour. But I did. What I did not try, because I'd seen others try it & invariably fail, was binge dieting. I changed what I drink (though not completely: I still occasionally have a little whisky), when I drink (though again, not completely: I still sometimes have a pint or two at lunchtime, though not a few times a week as I did 25 years ago), how often I drink, & how much I drink when I do. Unless you're one of those unlucky people who can't stop when they start & therefore have no choice but complete abstinence (& for them it has to be permanent, not short spells), I think this is the only way to cut down which works.
BTW, I've seen people I knew killed by drink, including friends. This is not a joke to me, or something for smug gloating. I tried to drop a heavy hint, perhaps clumsily, because I wanted to get across a message I think is important.
