Metronidazole
"I experienced a couple of side effects: metallic taste in mouth, sore throat, abdominal pain, loose stools, headache, nausea, lethargy, decreased appetite, AND a yeast infection at day 5! Side effects aside, this stuff works. All symptoms of bacterial vaginitis disappeared by day 2. Take some probiotics while taking this and hopefully you can avoid a yeast infection. Felt like the longest week of my life. I need a drink (you have to avoid alcohol on this)."
