As an alcoholic, not a good idea, we won't get the idea of the letter any better than a face to face conversation, especially if we are active in our addiction.
As a man, not a good idea. Men (as a rule) do not respond as well to the written word as women. There is a reason women buy 65% of all books and periodicals in the USA today, and that's because we men do not rely on written words for communication the way women do.
Regardless what you do, letter or face to face, have ZERO expectations, this way you won't be disappointed.
