sinusitis
"The first day it caused me very bad nausea. However I think it's because I had to take 2 pills on the first day per the instructions. On the 2nd day I had a bit of diarrhea but the nausea went away. I learned that I had to eat a lot to get my stomach full in order not to feel the nausea. Overall, this medicine worked in clearing up my sinus infection. I feel that on the 3rd day the medicine did its job and I started showing much improvement. (My fever had gone away after the first dose of medicine.)"
