The antacid is Gas-Hwal Myeong Su.

These days, I am on a diet. So I am eating healthy food, but sometimes when I eat greasy food, I quickly feel bloated and indigestion comes up.

In such cases, I take and drink Gas Hwal Myeong Su. Since it contains carbonic acid, I tend to prefer it more. It's easy to drink just like a soft drink, and as soon as you drink it, you burp and feel as if your stomach is 'unblocked.' Maybe because it's a digestive medicine I've heard of since I was young, I feel a sense of familiarity, so I think I drink it more often. If you experience indigestion after overeating, be sure to try Gas Hwal Myeong Su.
