I said "every second day" but that doesn't really cut it because I would usually binge drink several nights in a row followed by a couple days of abstinence.
A half a bottle of wine? Hah! If I drank a whole bottle of 13.5% red wine that would only be getting started. I usually avoided wine because it smells on you the next morning and leaves a semi-serious hangover. Besides, it's cheaper to get drunk on the hard stuff. Vodka was preferred because the smell of it is easier to cover up the next day. And boy did I drink a lot of that. They say that at higher altitudes you can drink less and feel it more, but when I moved from sea level to high altitude I didn't notice and never drank less.
