A condition affectiong conventioneers upon returning home. Symptoms include hangover (usually on the 1st day after return from convention) , lack of satisfaction in life because you're not at convention and checking the calendar every day to see how long until the next convention. Sufferers often write inconsequential messages on facebook or texts to other sufferers. This temporarily seems to provide some relief, but the effect doesn't last.
Sorry, I'm just not happy. I think I have Post Convention Depression Disorder.
