Metoclopramide
"I was given Reglan in an ER when I couldn't stop vomiting when I had a migraine. It helped to stop my vomiting, but I reacted horribly. It made me uncontrollably agitated and nervous. I couldn't stop moving, I couldn't think clearly, and I couldn't relax until I was given a sedative. I now claim that I am allergic to the drug due to the way my body reacted to it."
