Metronidazole
"I was given he the one time dose of 2000 mg to take at once. I had the pills a full 5 days before I said screw this fishy smell and milky discharge and just crushed them and downed them with milk. Truth, the taste is HORRIBLE!! Death in a pill! However, I had NONE of the deathly experiences so many of you have described. A little nausea and dizziness. The slightest though.. Like the kind u get from being too hot for too long. Nothing major. But it's been 12 hours now and the discharge AND fishy smell is GONE!! I'm mad I hadn't taken them already now, because I could be back to my regular, clear discharge. But I recommend it!!!"
