It's okay. Do not take medicine. Work hard on diet, and people who stay up late should also pay attention to strengthening physical exercise. Eat more foods rich in vitamin A, such as carrots, leeks and eels, and animal foods rich in vitamin B, such as lean meat, fish and pig liver. In addition, we should properly supplement calories and eat some fruits, vegetables, meat, eggs and other protein foods to supplement physical exertion, but don't eat too much. Eat some dried fruits, such as peanuts, almonds, cashews, walnuts, etc. They are rich in minerals such as protein, vitamin B, vitamin E, calcium and iron, vegetable oil, etc., while the cholesterol content is very low, which has a special effect on restoring physical fitness.
