Post Traumatic Disney Disorder.
I know it well. Each time I've come back from a Disney trip I go through a period where I don't want to talk or even think about anything Disney for awhile. Some might have noticed that the
trip report I posted from our last trip only included the first day (which I wrote up on the flight back home). After that I just did not want to deal with it anymore.
The only cure is time and planning another trip.
