I was taken to the er this morning. I woke up very weak, had nausea, could not stand up. I ha a hard time breathing. I crawled on the floor (to weak to get up) to my husbands room and told him to call 911. they gave me fluids intravenous and mentioned something about vertigo. I did feal dizzy, but the main feeling was weakness. I could not move my mouth, my face, and could not speak properly. Maybe a vitamin inefficiency?
