Thank you for the link, but it doesn't seem like it's answering my question? from your link:

"This study had various limitations that should be taken into account when interpreting the findings. First, we did not incorporate patterns of drinking, and therefore did not distinguish between individuals who infrequently engage in heavy episodic drinking and those who consume the same amount of alcohol over several days."

From what I'm reading it seems like the study was looking at habitual drinker, either drinking regularly or in big amount.
