Sounds like it was the syrup left in the cup. Its also possible that you felt sick from anxiety- seeing something you didn't recognize and wondering if you had done yourself harm. Its POSSIBLE.
But if it keeps on, go to the hosp. It could be the soda had gone bad from sitting too long.

its the aftermath of the coca-cola sticking around to haunt you...

POISIN! They finally got too you!! CALL A DOCTOR>!
