Eating peanuts and the drinking both can cause belly pain. This can be due to gastritis or hyperacidity or heartburn. Pepto-Bismol is an over-the-counter drug used for treatment of nausea, heartburn, indigestion, upset stomach, diarrhoea, and other temporary discomforts of the stomach and gastrointestinal tract. Ginger ale is often used as a home remedy to alleviate indigestion or motion sickness.
