urinary tract infection
"Never again, first 10'days macrobid. Still had infection.  Put me on bactrim.  I was so sick after day 5. I missed 7 days of work, I think 10 days was to much. Had loose poop, neasea every day, dizzy, loss 7 lbs in 7 days and the worst was the dry eyes and mouth.  I felt like poo. I thought I would end up in hospital.  It even made me depressed!  Never again!"
