There's tentative evidence for lots of drugs to help with alcoholism. Naltrexone has been generic for years and has been researched more for alcoholism and is prescribed for both alcoholism and obesity (I think in combination with wellbrutin for obesity). I would be very skeptical of talk of an extremely expensive drug possibly maybe being of use. And aside from being expensive, there's an ozempic shortage and some people can't get it for T2 diabetes.
