bacterial vaginitis
"Noticed unpleasant odor from "downstairs" so I made an appointment with my GYN who prescribed me 500mg of metronidazole twice a day (ended up taking pills 8 hours apart). Symptoms cleared up within 2 days of taking this medication. I experienced no major side effects from this drug (I was just thirstier than normal), but I have to agree with others, it does taste awful."
