I feel loneliness and boredom have him on the drink
Id imagine that loneliness and boredom can be triggers for returning to drinking, especially the lonely part. I mean, you can always fill your time, and not be bored, but it doesn't mean you won't feel a sense of loneliness. While moderation management may work for some people, Id suspect that it may not work for the majority of people with a substance abuse issue.
Interesting thing is that when youre treating someone with a sexual addiction, you dont completely eliminate them from having sex. That's unrealistic. You teach them how to have healthy, moderate sex (this will vary depending on the person), so it doesn't consume their life, and interfere with their daily function. If it can work for sex addiction, perhaps it can also work with alcohol abuse.
