I do but I have those troubles permanantly :( All the healthy things I can't eat, such as wheat, fibre, most veg, certain fruits, dairy, spicy or greasy foods to name a few. So I theoretically should be a size 8 cos everything I eat goes through me within minutes...supposed to take 24 hours to digest food, mine doesn't hang round long enough. Green veg and bizzarly even lettuce are amongst the worse culprits.
Try cutting dairy see if that helps as that is one of the worst things for tummy troubles. I drink soya milk, it takes some getting used to, but you can get it sweetened to get used to it. And you can get soya yoghurts/deserts as well.
I have to use codeine atm to help not be so loose, but it doesn't work as well as my usual tablets but its better than nothing.
Some people say the yoghurt drinks such as yakult help, might be worth a try. I can't drink them, has the opposite effect, but you won't know until you try. The more you worry, the worse it gets. Stress is one of the triggers, that started mine. Another legacy of my ex husband :(
