So absurd, considering the damage alcohol use has caused thus far, that he wishes to control his drinking. Absurd we think? Of course! We are hearing the musings, or quackings not of a recovering alcoholic, or even an alcoholic contemplating recovery. If an alcoholic has reached the point where control of drinking is possible, it would not be drinking. Moderation stopped being a viable option when the drinking continued despite the growing consequences of drinking. A desire to "control" drinking? No. It is a desire to drink wrapped up in flowery language.
BlueSkies1 nailed it.
