Alcoholism really is a disease. We didn't get it on purpose. But if we want we can give ourselves a really hard time about it so that we feel crummy and then find an excuse to drink. But we don't have to.
Living with the desire isn't easy, but it comes with the territory, though it eases up over time. Part of it is physical, and part of it is because alcohol fulfilled so many of our needs, or at least seemed to. Learning to live a different way means gradually getting better at it, so that we have new ways to feel good that don't give us hangovers in the morning.
One day at a time!
