Want to add that his mentoin if rock bottom and what sounds like your belief is inaccurate.
An akcoholic does not have to hit rock bottom. In fact there are plenty that never do.
So in him saying he just hasnt hit rock bottom yet is humorous since 1. He could have no bottom and things just get bad to worse and still drink and 2 even if he has a bottombut gasnt reached it yet....trust me when I say you dont want to be around for ut uf he does. Frankly its painful to witness alcoholism
