I was asleep for maybe a good hour and woke up unexpectedly. I had horrid chills, just could not stop shaking & my body was vibrating across the bed. I felt dizzy, my eyes would not stop scanning the room for a split second & I was so tense that I could not move, get out of bed or attempt to reach for my phone to contact anyone. I couldn't catch a breath or let out a gasp, all I could do was lay there and cry uncontrollably. When I was able to finally try to sit up the only response was vomiting and more trembling. I ate a small meal before bed along with a glass of orange juice and package of fruit snacks. I don't believe it had anything to do with my sugar or blood pressure. When I called my doctors office and spoke to a nurse all she told me was maybe it's a virus but she didn't know what to tell me because they were fixing to close.
