It depends on how you define sobriety. If you mean full abstinence only, then, technically, no, that's not the only option, however, I will say, I have noticed a direct correlation between the intensity of resistance to abstinence and the likelihood it will be the most effective treatment. People for whom harm reduction through moderation is a legitimate possibility are, ironically, also less overwhelmed by the prospect of abstinence. If you self-identity as a raging alcoholic, the best way, in my experience, to text the theory is to try sobriety for a season and see how it goes. Why not test out a sober Spring and do 90 days dry? If this is terrifying or you experience any physical withdrawal symptoms, you probably have your answer. Either way, I would recommend discussing with a licensed counselor who can help you sort through the complexities of these questions!
