Chewing and swallowing a spoonful of fennel or caraway seeds is a great way to stop indigestion. Along with this u can try the following things:
1. Try not to chew with your mouth open, talk while chewing, or eat too fast. This causes you to swallow too much air, which can aggravate indigestion.
2. Drink fluids after rather than during meals.
3. Avoid late-night eating.
4.Try to relax after meals.
5. Avoid spicy foods.
6. Stop smoking alcoholic beverages (if u do).
PS: If the problem still persist then u may need to see GP.
