I experience uneasiness/slight nausea commonly when i go out to eat (we do not use much salt at home). what causes this and how to address?

Intolerance: If you can't identify foods,drinks, or spices that trigger your symptoms when you eat in restaurants, it may be that your digestive system is thrown off by the routine of going to restaurants, eating later than usual, rushing around,etc. You could try taking a Dramamine tablet an hour before eating which may prevent the nausea reaction.
