I have a 7 month old who is way to attached to her pacifier. I want to wean her from it NOW. Advice? Help!?

We unfortunately introduced her pacifier as a newborn. Now at 7 months old she needs it to go to sleep. She wakes up in the middle of the night and cries for it. I go in, put it in her mouth, and she goes back to sleep - UNTIL it falls out again. Shes having some major sleep issues as it is, and Im just now starting to give her some "tough love"! I dont get her out of her crib anymore and comfort her every 10 minutes or so (on advice from my pediatrition). Anyway, we figure that since we are training her to not rely on mommy to go to sleep that we might as well take the pacifier away as well. Its going to be terrible though. Any advice to make this transistion go more smoothly?? I would LOVE any advice. Its going to be a hard few weeks and I need some sleep!
