People have asked me this before and it is difficult to answer, though I believe you can because the difference is that alcohol itself is not addictive, say such as nicotine as a product is. Alcohol becomes addictive because of the way we think, behaviours, etc, it provides a way to forget, suppress or to simply make oneself feel good about themselves at the time. Could be one, could be all and more or those reasons.
The thing with drinking alcohol is that you must know why you needed to have all or nothing... you must replace that need with other healthier methods. With this in hand, drinking alcohol then becomes more an ability of the mind to consume in moderation, to have limits. I don't drink everyday, even every week, but we may go out to a party where I will drink more than I would normally. Saying that... I couldn't drink much more than six drinks maximum nowadays, as I would be passed out from such an amount. When in moderation you must not get drunk... for example, I may only get drunk once or twice a year... the rest I drink only two or three and that is it. I may drink one a night for a week, then nothing for a month... always moderation is the key and it is a mental aspect, not an addictive property in alcohol itself. This is why you can drink in moderation if you really want to control it, though it is something you much learn to do slowly.
I disagree with the AA philosophy in the nothing at all to drink theory. If alcohol had addictive properties such as nicotine, then I would agree with it, though it doesn't. The behaviours need to be replaced with healthier options, yes. No alcohol would be required for a period IMO... even like drugs, a tapered system, not just a cold turkey method.
I believe anyone can drink in moderation... though is the occassional binge really a bad thing? Binge drinking is bad though it is meant within context of every week or the like, not once or twice a year when events occur. If you become destructive on alcohol, then obviously it is not a good choice to binge drink ever. If a specific alcohol makes you angry, ie. rum, then it should never be drunk.
Is a light beer a couple of times a week really a bad thing though? Not IMO!
