nursing to sleep

We have created a problem! I've always nursed Sophie to sleep. While she was little, she would just naturally fall asleep during her last feeding anyway. Then, it just became easier to nurse her while sleeping so I could get sleep. Now, she wants to sleep with us every night. And freaks out if I take my boob away. She instantly wakes up and the paci doesn't work either. HELP!!!! Please tell me I'm not the only one?!
