This is an understatement.

Drinking even moderately puts your body into a sort of fight or flight mode - the cells in your body will prioritize processing ethanol into acetic acid (vinegar) if they are able to do so; this predominantly occurs in the liver. Other cells will just die. Ethanol is toxic to pretty much everything it touches.

Additionally, drinking the way you said you were drinking puts you at significant risk for alcoholic ketoacidosis - if your body is using alcohol for its only fuel, it produces excess ketone bodies which make your blood pH acidic. This is a medical emergency and it will make you feel very ill. This occurs in alcoholics when they start to lose appetite as an initial withdrawal symptom - or forget to eat because they're too drunk.

It's also a neurotoxin, can cause pancreatitis (leading cause of this actually), kidney issues, digestive system issues, nervous system issues, and is really bad for your brain chemistry. End stage alcoholism is not a fun way to die.
