Eating something like bread before drinking alcohol will line your stomach, also drinking water between each alcoholic drink will make it less likely that you are sick or get a hangover. Mixing milk and alcohol is more likely to make you sick as the milk will curdle.
Belching, also known as burping, is the act of expelling gas from the stomach out through the mouth. The usual cause of belching is a distended (inflated) stomach caused by swallowed air. The distention of the stomach causes abdominal discomfort, and the belching expels the air and relieves the discomfort.
Answer Wiki. Could be several reasons why we get gas pains in the stomach, e.g. food intolerances, especially gluten and dairy, not chewing food properly, eating too late in the evening, eating when stressed. Antibiotic therapy can cause excessive gas build up due to antibiotics eradicating a lot of the friendly bacteria in the intestines.
