I've had trich once before. I took the metronidazole four 500mg tablets. It cleared up but took a good 3 days b4 I felt normal. I was being treated for a yeast infection, so I went through hell before the culture came back. DO NOT USE YEAST MEDS IF YOU HAVE TRICH. I literally had to use an ice pack, my vagina felt like it was on fire. Me and my friend were both treated and everything has been fine. I recently had intercourse with another friend, we used a condom but I'm wondering could I still get trich even with a condom?
