I don’t mean to come across as wholly dismissive of the potential benefits of pharmaceuticals, or the possibility of mitigating chronic excess. Whatever the method, deciding to seek help of some kind is a necessary first step.
From the abstinence-only advocates’ point of view (with decades of collective experience), the single most dangerously seductive idea of all is that an alcoholic can successfully drink in moderation, so their rejection of ostensible alternatives out of hand will be well nigh impossible to overcome. Once more comprehensive, long term, recidivism stats are officially in, however, it is, indeed, possible that naltrexone and/or other medications could revolutionize the treatment of alcohol abuse. It does look like collective or one-on-one support of some kind will always be part of the package.
Per the Director of NIH, and a scan of related trials, it appears that most of the existing research has centered on the effectiveness of naltrexone “as an adjunct to traditional treatment,” (presumably abstinence), while its effectiveness in a program of moderation has yet to be unequivocally confirmed at the clinical level. This doesn’t mean it’s not effective in that regard, but the problem with anecdotal success is that you generally hear very little about the failures.
I suspect that clinical trials like this one will eventually establish, and hopefully allow us to distinguish between those who can be helped to moderate their drinking and those for whom abstinence is the only solution. I have no trouble imagining potentially defining differences between, say, chemically acquired dependence and genetically compelling dependence (albeit in a more complex formulation). That would certainly be a welcome advance, but as the NIH Director’s testimony suggests, alas, remediation of the latter, short of abstinence, will be a long time coming.
I would, as you do, encourage anyone who thinks alcohol is, or even may be, a problem in their lives to seek help, because help is out there if they look – sometimes in unexpected places (like a message board!). You will generally be welcomed with open arms.
