Metronidazole
"So I began  having symptoms of an off smell but not full on BV. I could tell something wasn't right.  I told my doctor and he prescribed me metronidazole pills instead of the gel and told me the pills work better than the gel.  I have used the gel before and it seemed to work OK really didn't like the discharge that came with it.  My doctor prescribed me three pills a day 250 mg for 10 days. The only thing about this pill and I'm sure most will agree is the taste that is the worst however I wrapped it up in cheese, the cheese you get from the single squares, enough to fully cover the pill and I take it don't taste it at all. The  taste is the worst part not drinking is the second. Dark urine and occasional nausea but glad BV is gone"
