My opinion: everyday is a crapshoot with an active alcoholic or addict. I went from having a heavy drinker for a H to sleeping in a cot in the hosital while my doctor told me his liver is failing and he does not qualify for a transplant since he's a drinker.
Why are you trying to predict his future? I'm asking "softly" with care and concern ... we cannot even predict our future health? Is he worried about his health?
How are you doing?
