I feel fairly confident in assuming that ALL of you have probably experienced the pain of heartburn at some point. I used to get it really bad when I was pregnant. But the WORST culprit for me is eating spicy foods! Eating a spicy dish is almost guaranteed to cause me major discomfort. There are plenty of other foods that can set off heartburn too, like tomatoes, onions, chocolate, coffee, alcohol, and caffeine. Other heartburn triggers include dishes high in fats and oils, and certain medications.
