Metronidazole
"I was prescribed the 2000mg one time doseage. Yes the pills have a horrible taste but I'd rather taste that than have the symptoms of trich! I've taken the same meds for BV before and usually end up pretty tired after about 2 hours or so. I took this about 12 hours after a night of heavy drinking. Have felt a little nauseous and had loose stools and a little head ache. But it's been 3 hours since I've taken it and the odor is weaker and the discharge has dramatically decreased! Bye bye trich and bye bye cheating boyfriend that gave it to me!"
