Vomiting

Vomiting is a status affliction caused by eating old eggs, rotten comestibles, or tripe as a non-orc non-carnivore. After a while, it will cause you to become confused, then stunned, and finally pass out and lose a 50 points of nutrition. The final act of vomiting cures food poisoning, though you cannot count on actually vomiting before you die. A unicorn horn will cure the condition (and let you keep the nutrition).
