Alcohol is actually a pretty inferior painkiller since its mode of action is general anesthetic sedation rather than interrupting pain centers the way opioids do, and at doses to be effective is quite toxic.
In other words it’s a cute article, but absolute medical nonsense.
I disagree. I described my pain while driving home tonight. It was excruciating. I can barely feel it now after three small-medium sized martinis. It’s highly effective and, if you are in agony and you can’t get narcotic analgesics, it’s a darn fine alternative. It definitely works.
