This is not for me, but for my youngest daughter. She can suddenly stagger and then almost collapse. When she is helped, there is a strong odor of alcohol. She can be with me for a whole day, not drinking (which she doesn't so anyway) and this can happen suddenly. She has been to Emergency after collapsing in the street, but doctors are not prepared to believe her because of the odor, and a very slight elevation in blood alcohol. Can someone help me find a cause. I know there is one, and it has a name, but I can't find it.
