The DIS helps with withdrawals but here are other suggestions:
Order a copy of the WDW planning videos (if you don't already have them)
Make a scrap book with all of your theme park brochures and leave it in a convenient place so that you can get a quick "Disney fix"
Create a notebook with Disney ideas for future trips (must see or do, priority seating for restaurants you don't want to miss, park tours, etc.)
One thing DH and I had done was dedicate a book case in our family room to Disney souveniers but after our recent trip (BCV - DVC Member Cruise - BCV) we have decided to turn our office into our Disney room. This will become our Disney getaway while at home.
Good luck. Annmarie
