The sick feeling you get in your stomach when you realize it's no longer Christmas. Usually begins the second you open your last present and is worse depending on how excited you were on Christmas Eve.

Symptoms include: forgetting what presents you even got, sickened feeling, tiredness, depression, ect.
As soon as Sally opened her last present, she went in her room and slept. The poor girl's Christmas Hangover lasted a week.
