Coke syrup. You need to get it from a "old fashioned" pharmacy usually, from the pharmacist. Keep it on hand when you have kids, seriously. Seems like they're always puking.
You pour a small amount (barely a 1/4 cup) over a glass of ice, add equal parts of plain water, have them SIP (like one drink every five minutes). If that won't settle the stomach NOTHING will.
In a pinch you pour a cup of cola and alternate it between cups until it's flat.
Don't feed her until she's gone a minimum of 4 hour puke free, if you can get sugar water of some sort to stay down her she'll be fine for a long time without food.
If you have an organic grocery store there are natural ginger beverages actually made with REAL ginger, that's really good too but ginger has a funky taste that might make her hurl before she gets it down.
I realize NONE of this does any good now, but for future reference.
