Yahoo! News - A World Drinking Record: "Latvian police said a drunk picked up with around twice the blood-alcohol level considered deadly had probably set a world record but would wake with a hangover to match.
The unidentified middle-aged man was unconscious but stable after a blood test showed 7.22 parts per million of alcohol, police spokeswoman Ieva Zvidre said."

Zorak's highest recorded level was 3.3, tested 4 hours after I stopped drinking. That was pretty rough.
