Lance, I was so glad to hear that you were able to get treatment for Ember. My prayers are definitely with you. Autumn was on metronidazole back in October and she used to gag terribly sometimes because of the medicine. Apparently it tastes terrible. Our vet had us cushion it in the syringe between coffee creamer - I used organic half and half. Sometimes it wasn't enough though and she reacted pretty dramatically with choking noises. I have heard about some possible negative neurological side effects to the drug, but Autumn didn't have any. She liked getting the creamer. Her stools also firmed up soon after.
