If you feel nauseated, here are some tips: 1  Avoid foods that are hard to digest. 2  If the smell of hot food makes you feel ill, try eating cool or cold meals. 3  Eat six small meals each day instead of three large ones. 4  Do not lay down after eating. 5  Rest with your head higher than your feet.
Bland Foods. If the BRAT diet is just too restrictive for your tastes, try other bland foods instead. Ideas include saltine crackers, boiled potatoes, noodles or English muffins. But if you want to prevent another episode of vomiting, youâll have to eat them plain, so avoid butter, oils, sauces and cheese. If you canât get by on carbs alone, you might also try plain baked chicken or turkey. The flavor is mild, so your sensitive stomach should be able to handle it.
