Sensitive to onions

Thank you so much for your helpful messages, and I will certainly follow them up. Just knowing I am not alone makes me feel better, and of course if one can relax more, this has a direct influence on your stomach, though at times easier said than done!
Thanks again.

One of our family has this problem and I recently made a version of ratatouille without onion or garlic - aubergine, courgette, yellow peppers, tomatoes, olive oil, plenty of herbs (basil, oregano), VH vegetable juice, salt, pepper, dash of tabasco. He said he enjoyed it and had second helping. We all ate it, even DH who eats onions in almost every meal, and it tasted fine.
