Thank you for your comments. I appreciate them. Mar
Marion, it would be hard to guess without him seeing a doctor.
A simple blood test could show if he is in liver failure. For an explanation of how doctors diagnose liver failure, go to

Also---We have a cirrhosis and liver failure website at
http://homepages.about.com/imkindly/cirrhosis/
There is a page there called "Cirrhosis links", with links to good information on liver disease and symptoms.
I hope that you can get him to go to a doctor.
Good luck to you.
