Infant acid reflux HELP!!!

I have taken my son to his doctor and he has pretty bad acid reflux, he is 1 month old. He is breastfed. I have his bed at an angle, 1 bottle a day with rice cereal in it (recommended by his doctor), sit him up as much as possible, and he takes a medication 3 times a day. I'm also cutting out milk and all caffeinated drink from my diet to hopefully help. Any mommies have any other suggestions that helped your babies out with reflux??? (This is my second baby but my first with acid reflux)
