Help!!! how can i take the bottle away from my 15 month old?

I'm not going to lie my daughter is spoiled as she is my 1st. We took her pacifier at 2 months and she's been on a cup sense 6 months and has no problem, but we tried to take her bottle away at 1 year old and she screamed 3 hour straight every night at 3am for two weeks. She doesn't give in and I really need advice?!? I've tried everything including water in the bottle
