She has drunk heavily for a long time.
I know she has hidden bottles that her ex husband found, and I suspect she hides it to an extent to her current partner. I called yesterday morning and she was pissed, it was 10.30am. I have brought it up and she lies and says she has cut back, or wasn't drinking, or only had one etc etc. I have told her I know she isn't being truthful and she lies again. She also works shifts (midwife) and uses the excuse she's been working nights when she has clearly been drinking in the morning - I know one of her colleagues and know she isn't on nights as often as she claims. (I am not sure how often she drinks in the morning, but she certainly drinks heavily every night she is not at work.)
I have also told her that this isn't sustainable. I am her daughters godmother, btw (that is possibly irrelevant, I'm not sure!) She clearly doesn't feel able to stop and, despite necking at least 2 but usually three (or one box) of wine a night (and possibly now in the day) she has a remarkable tolerance. How long can someone continue like this before the health problems are irreversible?
AIBU to not mention it again as it makes no difference and the only person who can change it is her? Or AINBU to keep trying due to her daughter?
I have a feeling it's the former, but would like some other views as I am getting too frustrated to think rationally any more.
