That sounds like a case of food poisoning to me...that's usually the only thing that gets me going from both ends..where you know you're going to hurl because you get this wave of tingly neausia(sp?) first..
Did you re-heat the soup well? Boiled it forst? Sometimes anything that is chicken/turkey stock and meat based can go a little off if it's not cooled down quickly enough or no reheated properly. Just some thoughts.
