Hi B.,
I just went through a few ruff weeks getting my son off the bottle at night. He is three and last year I took the pacifier away, but then he used the nipple from the bottle. The suggestions that you received is really on target. Give him some warning that in the next day or two (whatever you decide) that it is going away. It will be ruff, but you just have to be strong. Maybe you can take him to the store to buy a special toy that he can sleep with at night or just something to play with it. My son has been off the bottle (I know it sounds funny) for several days now, but when it his really tired or upset he still ask for it. It is a comfort thing and it will take a while for them to stop asking.
Good luck.
