I have a hacking cough, clogged ears, loss of appetite and dry vomiting. Dylsum, nyquil, dayquil, and sudafed haven't worked. What should I do?

See your doctor. I would go and see your doctor or visit a med-check to see if you have an ear infection (acute otitis media) that would require antibiotics, especially if this has been going on for more that 3 days.
