Hi dp61,How right your description is..."I seem to have no control over it." Whenever I burp it's not me doing it...my stomach has complete control over the process. I can't make myself burp, but my stomach burps itself at its whim. I'm thankful that my stomach relieves itself in this way, though. (It's not a big issue, and doesn't happen constantly, but when it does, it's generally welcome relief.)
The fact that you can burp is a big bonus, although I'm sure it's hard to appreciate when it's bothering you. If you've read much at all around the forum, you'll have notice that quite a few people suffer with very painful bloating.
Both the bloating and the burping will resolve as you heal. You are right that what you're eating is the issue. It's really a trial and error process. As Baza said, it's very common to get back into bothersome symptoms after adding more challenging foods to your diet. If that happens it's best to back off to foods you were eating before the problem started up again.
Hang in there...this will all get better as your heal.
Best wishes,
Denise
