Would've have said flat Coke, but figure the Ginger Ale would do the same thing. The only other advice I can give is don't switch on daytime TV, that stuff will finish you off. Hope you're feeling better soon : )
Do you know why they recommend Coke when you have issues? Due to its high level of sugar. Whilst you do not eat or might loose the stuff you have eaten quite quickly you need to take care of hydration and some sugar. So Coke is not about getting the stomach any better but delivering some basics to the body.
I always have Activated Charcoal and Ginger caps at home. Activated Charcoal if I eat something that causes stomach issues and Ginger for nausea. Both available at most health food stores. Hope this helps.
Upset stomach that woke you up at 2am? Have you had appendicitis ever? It's most likely overkill, but if you haven't had it you may want to look into symptoms. My fiance woke up at 2am one morning with an upset stomach, went about her day for a few hours and was being operated on later that evening.
Works for my pups, but I'm not sure that's the best solution for you! I've heard apple cider vinegar will kill food poisoning bugs, but I suspect all it really does it make you vomit! Feel better... ~Alisa
