bladder infection
"I'm on day 2, so I have taken 4 pills and I feel absolutely horrible nausea.  I have aches all over like the flu and pains in my stomach, sharp ones.  I can barely keep my head up.  I am stopping them and going back to the doctor tomorrow.  I have never felt so bad, also very explosive diarrhea. I'm thinking of going to the hospital.  I feel as if I have been poisoned."
