Hi and Welcome. Have you looked at the SMART program? I think it's based on the premise that alcoholism is behavioral rather than a disease. No religious or spiritual component either.
As far as moderation goes, after struggling to try to moderate my drinking for many years, I realized I really didn't WANT to be a moderate drinker. What I really wanted was to be able to drink as much as I wanted with no consequences. I do enjoy the taste of alcohol, but honestly, I drank for the feeling it gave me. And moderate drinking just didn't do the trick. I doubt that will ever change for me.
