I'm pretty sure I've heard animal crackers can cause heartburn, oddly enough? My mom AND dad have pretty bag heartburn, I guess it's genetic. I've started to get it more and more. But my mom says the oddest things will give her heartburn. It all started, for her, when she got pregnant with me.
Pizza definitely won't do you any favors. lol.
My mom really likes Zantec. She's always got those pills as well as Tums on her.
