I don't think it is possible. Almost every story I've ever read on here involving "moderation" typically ends with the guy or gal ending up "right back where they started" in terms of drinking.
I think in the vast majority of cases, trying "moderation" just makes the addiction worse. We're not normal people, we can't "moderate".
Quite honestly, I think "moderation" can be outright DANGEROUS considering the very real possibility of triggering a second round of withdrawals. I had a ROUGH withdrawal, I wouldn't wish it on my worst enemy...... an awful miserable experience.
