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.
They can be caused by something as simple as swallowing air or eating the wrong foods. Less often, gas and bloating are signs of something imminently more serious, ranging from intestinal disorders to potentially life-threatening malignancies in the lower digestive tract, such as colorectal cancer. Common Causes of Gas and Bloating The two main causes of gas are swallowed air and the breakdown of food that leads to the production of gas. The latter is especially true when foods are high in sugar, starch, or fiber.
