Ill type more when I’m in a vertical position, or perhaps just off of the bathroom floor, but I wanted to vent real quick. You know what I’m allowed to take for nausea and an upset tummy while breastfeeding? Nothing. Not one damn thing.

According to MSN Healthy Living: “some over-the-counter drugs are useful for upset stomach and symptoms of reflux. These drugs include ranitidine and omeprazole, There is no evidence that these drugs are unsafe for breast-feeding women. Women who are breast-feeding should avoid drugs that contain bismuth, such as Pepto-Bismol.”
