Yeah, I have had the same thing you are describing. Maybe worse. All I could do was stay in bed. If I got up I got dizzy, nauseous and would throw up. SWMBO and my roommate finally got me some gatorade and got me to the doctor. I got some strong decongestants, some antibiotics, and a steroid shot. About a day later I realized that the right side of my face was paralyzed. The inflamation (or infection or virus or whatever) had caused the area around my facial nerve to swell. This is known as Bell's Palsy. After I realized that I didn't have a brain tumor, it was quite funny. This is the sickest I have ever been in my adult life and probably could have been prevented if I had gone to the doctor a few days earlier.
So, I would suggest to stay hydrated, get some nasal spray decongestant like Afrin. Also, go and give them your ID at the pharmacy and get the good stuff (pseudophed). And go to the doctor if it dosen't get better soon.
