What worked on my kids was diluting the bottle with water, so it's less filling and less tasty. It took a couple of weeks, but it became less wonderful and they eventually got over it. I diluted it gradually, until I only put water in the bottle, and something else (milk or whatever) in a sippy cup, and gave them the option of which they wanted (both at once was fine). Then they'd eventually just want the sippy cup, unless they really had a desire to suck on the bottle (of water), which was fine with me.
