We know a lady who blacked out and I don't even think she was drinking at the time though she had a drinking problem, she blacked out driving (thankfully, no one else was involved, I guess the car came to a safe halt), she had to go to the hospital or something, then, join AA and all of this. Severe alcoholics can have very harsh problems, DTs and so on.
So, Kavanaugh sounded like he is saying something like getting so drunk, you fall asleep, something like this. I can relate to that somewhat, your head is swirling, yet, alcoholism really is not the issue here.
