In a Youtube video {Leveraging Dopamine, 2023}, neuroscientist Andrew Huberman defines addiction as "a progressive narrowing of the things that bring us pleasure".
I worry that framing the goal as, "a lasting way to shift that to something healthier", will prime you to switch from one addiction to another. I would prefer for you to frame it as diversifying the sources of pleasure in your life and becoming able to take pleasure (and consequent to take interest) in practical things that you currently experience as tedious obstacles that must be endured so that you can get your next drink.
