this isn't really a question but you are correct. flat ginger ale can be good for nausea as can ginger tea. that's if the upset stomach doesn't have some serious cause of course.
will ginger ale settle an upset stomach. my mother always gave us flat ginger ale to settle our stomachs it has to have real ginger in it not just ginger flavored. it is really the ginger that settles the nausea feeling. she also taught us to suck on crushed ice to prevent dehydration.
