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.
Causes of Gas and Bloating. Bloating in the abdomen is commonly caused by gas in the intestines. One reason for too much gas is eating foods that create gas. Swallowing air while eating is often done unconsciously and may result in frequent belching during or after meals. To avoid swallowing air, slow down when eating, don't 'slurp' drinks, and don't talk while chewing.
