bronchitis
"I Have been taking Levaquin for 3 days for bronchitis.  Having difficulty sleeping and have no appetite, along with headache and a persistent fever.  Pharmacist never told me to take the medicine with a full 8 oz glass of water.  Might have been good to know.  So far, still have bronchitis, coughing up mucus and needing an inhaler.  I have never used an antibiotic that after 3 days I remain ill.  Jury is out however, as I may be better...soon I hope."
