Day 3 of sulfur burps HELP 🥲

I’m on my third day of non-stop sulfur burps. I think the offending meal was a bowl of Cheerios 🙃🙃🙃 I’ve barely eaten much else because I’m so nauseated from the burps. I feel horrible. They are SO offensive my god. I’ve tried kombucha, apple cider vinegar drink and walking/yoga to get things moving but nothing doing. Any suggestions to get rid of them please let me know 🥲
