My Brother and his friend drank this entire bottle last night. I told him that he has a problem and needs to slow down. Him and his friend go through 3-4 bottles of this a week. He said

"I don't drink too much, ask anyone who enjoys liquor and they'll say the same thing, IT'S NOT A LOT OF ALC FOR 2 PEOPLE"

I disagree. I have seen him drink heavier and heavier. We (the fam) and I are trying to get him to agree to go get help but he thinks this is a normal amount of liquor to be consuming. They also finished a 30 pack of beer. I'm hoping if he sees other people's responses, he'll be more open to help. BTW he's 24 still lives with us and has no job bc he sleeps all day due too being hungover but he thinks he has "sleeping problems"

So question: is this a normal amount to drink a night or is it too much. (I think it's insanely too much)
