The reason I wanted sobriety and only sobriety (though bonuses in other areas were quite welcome) was because I no longer wanted to drink. It was not that I no longer wanted the consequences—I had not wanted the consequences for quite some time. It was the experience of drinking itself I no longer wanted.
Sometimes people develop other problems, sober. Two years, five years, twenty years in. Food, sex, and romantic indulgence seem the most prevalent and pernicious. The opening conversation with such a person (as the opening conversation was once with me) focuses typically on the consequences. When that's the case, best to wait. The willingness will likely last as long as the consequences. As soon as the consequences abate, so will the willingness.
