Welcome FutureYesterday, lots of good comments here already. I am guessing this is someone you know and that you have a vested interest in their health/recovery?
In any case, as most here have mentioned what you call it is really doesn't matter. It's crystal clear to me that this person you describe has a very big problem with alcohol, and that not drinking any alcohol is likely the solution to that problem. And it's also almost universally true that someone who has a problem like this has the problem for life - AKA there is no going back to moderate/social/normal drinking.
