What does she eat for breakfast? Will she eat porridge? Both of mine sleep terribly and are grazing and hungry all day if they don't eat porridge for breaky, it is odd how much a difference it makes.
But I would try giving her more food, more often, through out the day, make sure she is really *done* when she finishes dinner.

Once you do that, you will probably find it easier to break the bottle habit, I would think. Is there a reason you don't offer her a cup of milk before bed, instead of sending her to bed with a bottle?
