Kissedbyfire, that's great he's 4 weeks sober and things are better for both of you.
In time with recovery, it's common to see alcohol as poison. It's how I see it now. Usually that happens with a recovery plan and time. But like Lexie says, he may be reinforcing (or tring on) his "I don't drink" vibe. Maybe self righteousness is how he deals with being surrounded by alcoholics right now. It wouldn't surprise me at all if they try really hard to get him back in their "fold." His sobriety is bound to be unsettling to them, because it forces them to give their drinking a little thought.
