I don't consume alcoholic beverages anymore (and haven't for nearly a decade), but I certainly did consume quite a bit of beer (and other alcoholic beverages) for more than four decades, and without a doubt, I would have been more "linked" to the Hemingway category.
My personality changed little, regardless of the amount of consumption, and I don't tend to have perceived emotional mood swings. For example, my attitude -- outwardly, at least -- wouldn't seem much different if things were going good or bad in various venues (including such places as bowling centers or dog tracks).
