Thanks, jennikate.
My understanding of OCD as an illness, is that kind of obsession has no relief, and no workable remission. OCD can be of course managed, and yet the obsession continues unabated. A very challenging illness, to be sure.
My understanding of the alcoholic mental obsession, is it can be abated, and even banished, from our daily living experience. I would agree that the anology you have shared shows your acceptance that both obsessions indicate disordered thinking, and perhaps that is where it starts and ends. You've graciously allowed for any misunderstandings in your post, so way awesome on you.
