It’s important to keep replacing your body’s supply of water and electrolytes, which include sodium, potassium and chloride. Mix up the perfect electrolyte drink by stirring a half-teaspoon of salt and four teaspoons of sugar into a litre of water. Add a little bit of orange juice, lemon juice or salt substitute for potassium. During the day, drink the full amount. Start eating only foods that are see-through, like chicken broth and Jell-O. Broth is an especially good choice, since it supplies your body with water as well as electrolytes from the salt. Stick with these “clear foods” for a day or two. Avoid fruit juices. Fructose can be hard to digest. Eat plenty of bananas,boiled carrots and rice.Avoid apple juice.Avoid foods that are rich in roughage, which can be hard to digest ie.,beans, cabbage or sprouts.
