The first way to relieve a hangover is to drink more water and urinate and defecate more often. A lot of alcohol will remain in the intestines and stomach when it exceeds the load of the liver. Through urination and defecation, some of the alcohol can be excreted, thus relieving the stimulation of the intestines and stomach and improving the hangover symptoms. Second, drink some yogurt to protect the gastrointestinal mucosa, reduce the absorption of alcohol, and also relieve the stimulation of alcohol on the gastrointestinal mucosa, thus relieving the abdominal pain or diarrhea caused by a hangover. Second, take medicine to relieve. The ethanol in alcohol may enter the brain with the blood circulation, stimulating the cerebral blood vessels and causing spasms that lead to headaches. You can also use some painkillers and spasm relievers, such as ibuprofen, to improve pain and relieve hangover symptoms.
