Tinidazole
"Within 10 minutes of taking the pills I could taste the metallic taste. It was not unbearable. BV was gone when I was done with the 2 day treatment. Make sure to take with a very large meal! I think this is what saved me from vomiting. I have a very sensitive stomach and only felt nauseous a couple times but it went away quickly. Only other side effect was that I was very fatigued."
