Since yesterday I ve experienced some slight dizziness. This morning, I woke up feeling fine, but by 9:00a.m. I was feeling nauseus and have had a dull headache. My head feels like it s full and heavy, but I m not congested. I have no appetite, and couldn t even drink my morning coffee. I had to leave work, and have been home resting. I was dizzy even when I think I had fallen asleep. I thought it went away, but now it s back. I feel lethargic, nauseus, dizzy, and my head feels heavy.
