Yes she sounds very like my dad. I had though of sending a mechanic round to take out the battery in his car but he would just find other ways of getting drink.
His kidneys failed a couple of years ago, he is in the UK so it's all paid for by the NHS, including carers etc so it won't be stopped. It probably should be as he has used tens of thousands of pounds and countless hours of many doctors and nurses time that could be spent on non self inflicted illnesses but if it was stopped it would be a death sentence.
