Does anyone know why I can smell my boyfriend's seizures days before they happen? So my bf just had a seizure (6/22) and on Friday (6/19) I told him that I could smell it coming. He originally didn't believe me but this is like the fifth or sixth time this has happened. He doesn't understand how and honestly I dont either. I compare it to how I can smell people with diabetes in a way that no one else around me will be able to smell the same thing. UPDATE: 9pm We were sent home...
