I too suffer from a WB addiction, mainly since I hate being on an island, makes the game so boring until I can get ocean ships (aka, 300 turns on Realistic), that and late game when I almost destroy a rival I give him a some extra land... maybe an island (more people to slaughter if they really annoyed me.) However to break my addiction, every time I WB I lower the diplomatic rating of me by a few points in every nation. Makes me think twice to WB when monty is my neighbour.
