Moderate Alcohol Use

He drinks a lot. His preference is Vodka, but for some reason yesterday it was brandy. He works a full time nite job and is very well off. How he keeps a job drinking the way he does is beyond me.
On Sundays, he starts out drinking and passes out, then he wakes up and eats, cleans house, and takes care of bills, mows, then starts drinking again until he passes out again. He usually goes to bed around midnite every Sunday nite and sleep until around 4 or 5 on Monday afternoon to get ready for work. He says he sleeps 16 hours plus because he is exhausted from his job. Right now he is still sleeping and he has been in bed since last nite at 11 pm.
Is this a symptom of alcoholism or is he just tired?
He nearly died a couple years ago from drinking. Literally in a coma for a month. He will never get help. He gets no support from his adult children who just dont get it.
I learned….I will never drink, not even a glass of wine with him again. I cant make him stop, but I dont have to partake in his problem and pretend like its not there.

Take it from someone who is in recovery. He needs help but he will get it only after he realizes it for himself.
