At this point my daughter does not have acid reflux that I'm aware of. I talked to my mother about the Prevacid b/c she takes it too but for Gastritis. She said if she takes it like she's suppose to, 30 min. prior to breakfast, it makes a huge difference in the way her stomach feels all day long. Morgan's doctor said she's taking in a lot of air, her chest x-ray always shows lots of air in there. She's actually been taking Prevacid for quite a while and I've been giving her 15mg 2x/day. But I never knew I was suppose to give it to her 30 minutes prior to meals. She's still eating very well today and her stools are good. I've also noticed the last 2 days that she's had no gas, which is big b/c she always has lots of smelly gas.
