I often see "food" 2-3 hours after eating.
This specific instance was different because it was accompanied by vomiting. As runny as diarrhea can get while vomiting simultaneously. 3 of 4 of us got sick. All three that had the same soup from a hibachi style restaurant.
I got sick about 3 hours later and my wife and daughter the following morning.
All throwing up and vomiting. Mine lasted about 24hrs. Theirs a little longer.
I had been out of town, this was the first meal we had together in 4 days... it was food poisoning.
Tried not to be too gross with details. Sry.
