bacterial vaginitis
"On day 5 of 500mg/twice a day for a week and it cleared up my discharge/smell/itchiness within two days so it definitely works.  These comments terrified me when I read them the day I got prescribed this medication but my side affects haven't been as severe as these. 

I've had the unpleasant taste in my mouth nonstop, even with taking the pill with juice and not letting it touch my tongue. Had cramps and nausea on day 3, but I also didn't take it with as much food as I normally have been. The last two days I've had severe fatigue and exhaustion to the point of almost being unable drive my car. Overall, the worst side affects I've ever had to a medication but they are tolerable if you follow the instructions exactly as prescribed!"
