So I used to get sulfur burps - when my Crohn’s disease would flare up, my gut slows way down, first loose stools then nothing. After that cramps, burps, and then vomiting. I found that sugar/carbs are the problem. More sugar the more inflammation. Turmeric helps with inflammation but needs large amounts sustained. Prednisone is a miracle for reducing inflammation but there are long term side effects.
