Hi passionfruit!
It seems to me by reading the experiences of the alcoholics and addicts on those threads that there typically is an underlying issue, and that drinking is just a symptom of that problem.
That said, "I hate my job" seems to be just an excuse and a way to lay the blame. Perhaps the best response might be something along the lines of "Oh, I see.'
I hope your husband continues on in his program!
Hugs, HG
