bacterial vaginitis
"Bacterial Vaginitis is not uncommon, taking a daily probiotic with a high number of live bacteria (the beneficial bacteria in yogurt) greatly reduces the risks of getting bacterial vaginitis again. My boyfriend and I are very active, usually daily, and  like clockwork I was having to treat bacterial vaginitis every 5 weeks for nearly a year. Each time I was prescribed Metronidazole 500 mg twice daily for 7 days, each time by day 2 the odor is gone. The medication is great, the taste is terrible so I suggest putting the pill into the back of the throat onto a mouthful of already chewed, ready to swallow food without allowing the pill to touch any part of the mouth, it helps! Douching isn't recommended, rinse out in a bath."
