How do I wean my 6 month old off night time bottle?

My son was just recently very sick and needed his bottle more often for comfort, since he doesn't take a pacifier. Now that he's better, he wakes up every couple hours in the night crying because he wants that suction from his bottle. I am getting very tired and would like some help on how to break him of this. Before he was sick he was almost sleeping through the nights without it.Could I now start giving him a pacifier? Please help.
