I also began my countdown at about 4 months out, and felt like the day would never come. As you can see I'm only 10 days away from WDW!!
I do visit the boards everyday, multiple times a day. My advice is not to try to distract yourself, but continue visiting the DIS, read lots of trip reports and enjoy the excitement of planning and waiting for the day to come. They say half the fun is the planning and anticipation of the trip. Good luck and hope you have a great trip!
