I'm very dizzy, I can't see straight, I looked in the mirror and my eyes are a little more than half way dilated. My dizziness has given me a headache so I took some pain medicine, Tylenol, to see if my headache and dizziness would simmer away, but it hasn't. I've also been drinking lots of water and laying down to, I also feel tires, but I had a lot of rest today. What could this mean?
