Metronidazole
bacterial vaginitis
"This medicine is great at killing infections. I had bacterial vaginitis pretty bad and by day two the symptoms were gone. I'm on day 5 of 7 day treatment of 500mg twice a day and I haven't had much symptoms till tonight. Before I was feeling some dizziness, some fatigue and lack of concentration. I was also suffering from very uncomfortable constipation. Tonight after taking it I've felt nauseous and my stools are starting to get softer. I'm really afraid to take it tomorrow for in fear of how bad it will make me feel. "
