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.
Bloating and Upset Stomach. Gas has buoyancy and gas pockets can become trapped in the upper and lower intestines. The gas acts like a cork, impeding or halting the flow of gastric juices and causing pressure to be built up. This pressure causes painful bloating and swelling of the abdomen. When gas pockets form in the stomach, this can cause the stomach to distend, causing discomfort or pain.
