You are talking to your new patient, John.  He's a pleasant 30 year old man who, by your estimation appears to be a victim of HGS... Holiday Gluttony Syndrome.  John presented to you in the ED with abdominal pain, nausea, and vomiting.  He goes on to tell you all this started after he chowed his way through a few too many Buckeyes.  You see every Christmas, his mom sends him a far too large tin of Buckeye candies, which John had eagerly eaten and eaten and eaten, until the belly pain hit.
