Don't count on milk. Milk often hinders rather than helps stomachs because many people can't digest it easily. Though many people think milk can soothe an aching tummy, it actually may do more harm than good. People who are lactose intolerant have trouble digesting milk and end up with bloating, gas and cramping.
Ease up on coffee, alcohol and smoking. They irritate the stomach lining. Even decaf coffee bothers some people. And if you smoke, you can add this to the very long list of reasons to quit.
Drink plenty of water. Aim for six to eight glasses of water a day to keep your stomach and intestines running smoothly.
