Be careful with that. The hangover provides a negative feedback that keeps the vast majority of (any)-alcohol consumers from becoming addicted. Now leave that out and see what happens.

Note: Alcohol hangover is not the same as the immediate withdrawal symptoms of other drugs that let‘s you crave for taking another hit shot whatever. It‘s caused by the myriad of trash by-products in metabolizing ethanol, not for the lack of alcohol. (and for certain alcohols additional also tannins, aroma substances and similar - think of whiskey and cheap wine)

And, I suppose, more simply, the diabetus! Pickles * beer^2 * burger * fries = (sugar * fat)^2 = pike of insulin over several hours * abundance of bad fats that the liver is supposed to absorb. I do realize not every alcohol binging happens in this form, but it’s the classic modern/hipster form. Any such behavior, even without alcohol, would turn the liver upside down.
