I guess it doesn't take long to fall back on old habits when you're in the trenches though. A lot of translated intercepted calls posted at https://www.youtube.com/@insightsfromukraineandrussia and reports from the front line talk about drunk Russians like it's an epidemic of alchoholism. They also talk about drunk Ukrainians on another one of the podcasts I follow so it's not only the Russians drinking on the front line.

That being said, I have a few Russian friends that immigrated years ago to Florida and they're not big drinkers. They were all from well off families though. Kinda like here, I suspect alcoholism follows poverty.
