I like the idea of changing the routine around drinking:
Keep your booze in the basement/cellar/attic;
only buy one bottle at a time;
if you're close enough always walk to the store to buy alcohol;
or make yourself park 4 blocks away and walk then;
change glass style and size (smaller?

);
change what you drink to something you don't like quite as much.
Or only drink with food;
or only drink between 4 and 9 then force a quit.
When eating out force a change by having a dessert wine after the meal instead of red/white with the meal.
Make yourself measure with a measuring cup every drink you have for wine, and a small shot glass for booze.
How about a change in time of taking pill? Can it be put off for an hour, then another hour? Those two hours are not used to drink, but we can still have a drink later.
I kinda like the idea of walking to the store for each bottle. I don't walk much because of pain but if I wanted a drink I'd sure get my but down there!!
I think anything that shakes up the routine will at least make us conscious of what we're doing - might help with
gentle control of quantities.
