Hello Callapitter and welcome to HealingWell. Sorry about
your bother.
Let your brother know that he is not fooling anyone but himself. He is actually robbing his self of more time on earth. My husband did that exact same thing. His doctors knew. Even if his blood tests come up negative for alcohol doctors can tell by a number of other symptoms as to whether the patient has in deed stopped drinking. Have a heart to heart straight talk with your brother. He will probably have to go to AA before they will list him even if he is a good candidate. He needs to stop now and get his priorities in order or he is going to lose any chance of a longer more productive life.
This is one hideous disease. But with a transplant he can have a new chance at life. It won't be easy but it will be well worth it if he gets a liver transplant in time. It is not fun trip for the patients or caregivers.
Show him this website. Have him read a few of the posts that you have read. You can lead a horse to water but you can not force him to drink. But in this instance shove his head into the pail if you have to. Take care and Good luck!
