Please cross post this in the Cirrhosis of the Liver community. The Community Leader there, Hector, will be able to help wrt options for your husband. He can still be helped, but must show 6 months of documented sobriety. And many times, simply stopping the alcohol will allow the liver to recover and last for many more years. But there must be real changes, or the end will be near.
He has to STICK to a strict diet...plenty you can find! Most of all NO ALCOHOL!! Not even 1 beer!
