Thanks for the responses all.
Peacefulwater - I retired early (long story) but with no financial concerns so I was lucky. I don't drink more now than I did when I was working - if anything these days it is a tad less if anything. But the pattern of my drinking - cracking open a bottle of wine every evening at about 8.30, waiting for the mild euphoria and release of all my cares and anxiety by the second glass and getting through the rest of the bottle and then a bit more - only to wake up unrefreshed, a bit wobbly, and spending the day feeling dreadful, full of fear and anxiety, feeling vaguely unwell and just waiting for the same time that night to open a bottle again for it all to go away again - that pattern has had me in its grip now for well over a year. It has made me unhappy and miserable and as I'm in my 60s anxious about its effects on my health of course - and anxiety fueled by the alcohol itself of course. Time to get of the evil roundabout.
