trichomoniasis
"The taste is unpleasant, though not as unpleasant as trichomoniasis. Upon the first dose (500 mg) I suffered from flu like side effects. My neck grew stiff, I felt feverish and steadily nauseous. It did not cause me to lose my appetite, despite the nausea. Headaches became common, along with an undying thirst. Having to go to work on this medicine was as difficult as a virus. I had trouble sleeping to the extent that I actually had remained awake for over thirty hours before falling asleep. It was around the third day in that I suddenly had thick, white discharge that had a musty odor, however that only happened that one day. It is a rough pill, but it gets the job done. No pain, no gain, as they say."
