How to stop burping
Burping usually starts after you eat or drink. If you’re burping a lot after a meal, you can try the following treatments to help your stomach release the excess air:

Walk around or do light aerobics after eating. Physical activity helps with digestion.
Lie on your side or try a knees-to-chest position like the wind-relieving pose until the gas passes.
Take an antacid to neutralize stomach acid and prevent heartburn, which can cause burping. Bismuth subsalicylate (Pepto-Bismol) is particularly useful if your burps smell like sulfur.
Take an anti-gas medication like simethicone (Gas-X). It works by binding gas bubbles together so you have more productive burps.
Drink ginger tea after eating. Ginger may help relieve gastrointestinal irritation and prevent stomach acid from flowing back up the esophagus.
Chew fennel seeds after your meals. Though not backed by research, fennel is thought to help expel gas from the intestinal tract and assist digestion.
Sip on chamomile tea. It’s believed to help prevent acid reflux.
Limit activities that cause you to swallow air quickly, like laughing and drinking too quickly.
