Nausea and regurgitation the day after getting drunk can be relieved by considering diet therapy and medication such as domperidone and omeprazole. 1. Dietary therapy: Eat foods containing organic acids, such as citrus and apples, etc. Organic acids can have a chemical reaction with ethanol, which can help relieve nausea and regurgitation after drinking. Drinking more water also helps to speed up the metabolism and discharge of alcohol. In addition, drinking honey water can also help relieve the discomfort caused by drunkenness. 2. Medication: Domperidone can be taken orally to relieve nausea and vomiting, and metoclopramide can be injected intramuscularly if necessary; omeprazole, magnesium aluminum carbonate and other medications can also be considered for treatment. Drugs should be used under the guidance of a doctor. If nausea and regurgitation occur the day after drunkenness and continue unrelieved, it is recommended to go to the hospital.
