I just decided that the amount he was drinking (at the time 3 liters of beer a day) was enough for me.
Slightly OT, but I've always been amazed at the volume of beer some people are able to consume. When I was a teenager, there was a middle-aged guy that I worked with, and on his days off, he would drink a whole case of beer in one afternoon.
My AW doesn't drink quite that much, but on the days she's drinking beer instead of Vodka, she'll easily put away six or seven in a row without pausing. I just don't see how a person can drink that much of anything without getting bloated, but they do.
