I've been living with the exact same situation. I've started avoiding all FODMAPs (including garlic) and it seems to have helped. But, it's very hard to do since so many processed foods and restaurant meals can seem OK but turn out to have included an ingredient on the "avoid" list. And if ingredients say "2% or less of ...", I'm neither sure how much the package contains in absolute % nor relative effects. So when I do have an outbreak despite trying to be careful, I am never sure whether it invalidates my hypothesis about the cause or indicates I just wasn't careful enough.
