The first time she consumed it, it was too much at once. The second time she took her time drinking the bottle. Sometimes when you take in a load of nutrients, and you are not hungry to death or something, your stomach decides to reject the food because it is more than it can handle. This also happens when you go through rapid temperature changes or when you lose your appetite.
