I lost count after 4 weeks. Go to your doctor and ask for an x-ray of your chest to also make sure you don't have puemonia.
I have had very bad allergies this year and have had to get a steriodal inhaler as well as my original inhaler. Musinex did not work for me or my son. I lost my voice for about a week and a half, then off and on after that so far. I am taking 2 allergy pills, 2 nose sprays.
I'm sorry you have had to go through this stuff. Antibiotis don't work on allergies (hayfever, pollen, etc.)
