I’m about to go to the cinema so I can’t find you references, but there’s a lot of anecdotal evidence at least of glp1’s curbing all sorts of addictive behaviour. I personally started Mounjaro last week and my coffee cravings have gone way, way down for the first time in my adult life.
I believe there is, I don't recall the source but have read that these drugs work by reducing cravings. So they have shown at least hints that they can work on any addictive behavior, not just overeating.
