She would experience intense abdominal pain at first. She would then begin to feel incredibly nauseated as well after about ten to fifteen minutes, if only a small amount was consumed. Depending on how much she ingested, she would eventually be forced to vomit, possibly violently. If enough was ingested (say, two glasses worth), the effects would be much more severe than her body attempting to merely expel it: she would be wracked with pain throughout, and feel much, much weaker, and her lungs would begin to burn. She would be wracked with fits of coughing in between throwing up, and there would be some of her OWN blood mixed in with quite a bit of the upset. She could also potentially develop blurred/double vision, difficulty in swallowing, and muscle weakness.

While she would have to ingest a lot of it to die, given what she is, she would still be made incredibly uncomfortable from it and probably end up sick for at least an hour or two depending on how much she ingests. Even once her body begins to recover from all of that, she will probably be left feeling very weak and slightly dehydrated. (The atmosphere of the Dark Hour will likely not help with this affliction.)
