bacterial vaginitis
"Prescribed 500mg 3x a day for BV. Day 1 I took two doses 8 hours apart. Awful, chalky taste that you can't get rid of. Slight dizzyness and slight headache day 1. Day 2 woke up with the edge of a headache, ate my breakfast and took dose 3.  Headache developed into the severe/persistant headache that would not respond to any meds and is a "call your doctor immediately" side effect. Developed into one of the worst nausea migraines I have suffered in a very long time.  Doctor said to stop med and go to ER if headache got worse.  Improved my BV symptoms that fast, but I can't take this med. Caused insomnia, restless legs, severe headache, dizzyness, nausea, dehydration and loss of appetite, Those who react badly are not being melodramatic."
