Bananas. These potassium-rich fruits contain magnesium, which can help calm an upset stomach. Crackers or dry toast. Nibble on either if other foods make nausea worse. Eggs. Eat fried, scrambled, or in an omelet. Eggs contain cysteine, which helps break down some of the toxins alcohol leaves behind. Nuts. A handful of almonds and walnuts contains the healthy fats and protein the digestive system needs after a night drinking. Oatmeal. A bowl of plain oatmeal provides minerals and B vitamins, and it is bland enough to eat with an sour stomach. Add a few banana slices for extra flavor and nutrients. Pickles. The sodium content in pickles gives the body what it needs to rehydrate and get the digestive juices flowing again. Watermelon. This fruit contains antioxidants and water, which helps restore balance to the stomach. Coconut water. Full of potassium, electrolytes, and other nutrients, coconut water helps the body hydrate and might be more palatable than plain water. Tomato juice. Tomato juice stimulates liver function, which helps the digestive system process and eliminate alcohol. Ginger tea. Ginger helps calm a queasy stomach. Kombucha. This drink is full of probiotics and it helps detoxify the body. Its fizzy nature might help relieve symptoms associated with nausea. Sports drinks/electrolyte drinks. Because these kinds of drinks have electrolytes, potassium, and other nutrients, they are good options for staving off any queasiness from a night of too much drinking. Lemon juice. Lemon juice squeezed in a glass of water or a glass of lemonade helps neutralize acids in the stomach. Water. Alcohol dehydrates the body, so water is one of the best things for a hangover. Sip slowly and frequently to rehydrate and keep nausea at bay.
