I was prescribe metronidazole 400mg, 5 pills at once as a single dose for bacterial vaginitis. I accidentally took it twice. 5 yesterday and 5 today. I made a mistake and forgot it was a single dose. It's been 8+ hours since I took the second dose and I feel okay. A little dizzy slightly shakey hands and a tiny tiny bit nauseous. Just drinking lots of water and going to fall asleep now. Will I be okay?
