I usually drink a large cup of coffee and 1 liter of water until 10 a.m. Have to pee all morning.

Without a doubt, but if “I’m having to pee all the time” is your only symptom, I’d worry about a dozen other things before straight blaming alcohol intake (provided you are not constantly intoxicated as alcohol is a diuretic). Do not get me wrong, if you think you are drinking too much you almost certainly are, but alcohol abuse disorder should show up in a ton of places before getting to kidney damage levels. In fact, the opposite is significantly more worrisome: If you drink too much and have a sudden reduction in amount of urine, that’s the big alarm bells for Acute Kidney Injury.
