I am so sorry to hear about your wife....what a tragedy! It is horrible to see someone in the hospital with that sort of muscle mass wasting and lack of recognition knowing it was all self-induced.
When my stepson was in the hospital about 10 years ago, he was given a 50/50 shot at recovering from alcoholic hepatitis, jaundice, and the DTs. He experienced some incredibly paranoid hallucinations, had a couple of liters of ascites fluid removed from his abdomen, and had pronounced muscle wasting in his arms and legs due to his drinking. He was told by his doctors that he could not drink again because his life depended on it.
Amazingly, he survived to drink and do drugs to this day.
I will pray for you all for the best possible outcome. I am so sorry.
