bacterial infection
"The side effects!!! On Day 2 I felt nauseated throughout the day then at night the vomiting started, diarrhea followed. I suffered through but the next day I was rushed to the hospital. I was put on IV fluids and stuff to stop the vomiting. It has been 3 days  since I stopped taking it, still battling with my appetite and the sour taste in my mouth as well as fatigue."
