Just throw it out, she'll get over it.
From working in childcare I got the impression that children aren't really addicted to pacifiers so much as their parents are.
We had a half dozen children in our room who's parents had gone on and on about how they NEED their pacifiers, they dont sleep without them... we never once gave any child in that center their pacifier and never ever even once have I seen a child even ask for it during the day, or cry because they didn't have it. The parents seemed to have created the addiction. Now, thats not to say its not real, because with you she knows she can get it, we did have one girl who would go to her 'school bag' as soon as her mum arrived and find her pacifier and pop it in her mouth, when she didn't do it at all during the day, because she knows mummy lets her.
With any change, expect an upset, just be strong in yourself and she will move on and forget about it in no time at all.
.... although.... I will admitt after having seen that I was never ever going to use a pacifier, but I was given a couple as a gift... and in the middle of the night with a screaming baby, they become very attractive!
