Metronidazole
"I stared taking this drug for BV, even though I didn't really have symptoms of it but my doctor tested me and it was present. I had HORRIBLE diarrhea, nausea, back pain, and tiredness. I would take it with a full meal and bread everytime but my stomach was still upset. I am on my 4th day out of 8 and I hope I can handle taking the rest of the pills. Take with a huge meal and lots of bread or crackers and hope it doesn't make you sick!"
