I've suffered from stinky burps for years, usually every 6 months. I finally found a solution, hope it helps someone else out there. The problem is too much bad bacteria in your stomach and intestines, and not enough good bacteria. Eating sugars just feeds it and make it worse. Now I can make it go away within 2 hours. I take several Standard Process brand Gastrex, and Lactobacillus acidophilus capsules, and it goes away. I also eat yogurt. If I'm hungry I'll eat chicken soup.
