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.
