Do you mean treatment for her alcohol issues or some conditions or illnesses you think she has? Is there a diagnosis in place?

Well is she willing to get treatment? It’s hard to suggest anything without knowing what’s really going on. Sure I’d say she’d benefit from therapy and attending AA meetings. But it has to come from her, not you

As about personality change... I rarely if ever touch alcohol but I can ensure you that after three drinks or more, I’d be acting totally different than as if I was sober. That’s what alcohol does.
