Lizy, how did you stop the pacifier? For my nephews, I make them stop using it when they stayed over at my place.
What I did was 'brainwash' them for a week. Tell them that they are big boys already, pacifiers are for babies and they don't need pacifiers anymore.
Then keep counting down and telling them that they'll have to give away the pacifier to a baby on Saturday night.
On Sat night, they actually 'gave' the pacifer to my other nephew who was an infant then.
And they never asked for pacifier ever again. And when they went to bed, I will sing to them and sometimes they are not asleep yet, I will just tell them to lie down and don't move. After ten minutes, they will drift off cos nothing to do
My friend stopped her girl's pacifier rather abruptly and her girl could not sleep well for almost a month!
PS: The tried and tested method to make them sleep early is to tire them out. Before I sent my boy for classes, we will bring him to the playground and let him play for 45 min to an hour a day. We go just before dinner (when there are many other children at the playground to play with him - I can just sit at the sit to monitor), so he comes back to shower then eat. Then we'll do reading and he'll fall asleep very quickly after that.
