Some of us refer to it as Disneyitis. There is no known cure. But the symptoms can be treated in many ways. These are some ways we have found to ease the pain.
Spend time at your local
Disney store, read the latest issue of Disney magazine. When a current magazine has been read, re-read those old back issues(I refuse to throw them away for fear of recurrence of the disease)
Other ways....watch a Disney video with the kids that you have seen at least 10 times before, wear something Disney related everyday of the week(these make you feel all warm inside), dig out those old scrapbooks of past trips to WDW, start a new scrapbook of those 300+ pictures you took on the last trip(this has a tendency to take time, therefore it has a longer lasting effect), get together with other DISers, they understand.
There are many many other treatments out there but here are the top 3......
Planning that next trip, spending vast amounts of time here on the DIS boards, and actually being in WDW in the warm sun.
Just remember, you are not alone, we are here for you.
