Hi,
I've no idea whether an alcoholic can ever "do" drinking moderately, anything is possible and people are different, plus I'm not an alcoholic.
But I would have to ask.......(at least to myself) if someone is so certain that they can control their drinking and moderate successfully why on earth didn't they do that in the past??
and if she lost everything because of alcohol, why would she want to risk it.
I can drink moderately, but I don't have to plan it or control it or moderate it, I don't have to think about it at all, but like I said I'm not an alcoholic.
So what are you going to do if she does (sorry I don't know your story),
good luck
