trichomoniasis
"About 2 weeks ago I had sex with my friend. 3 days ago my vagina started itching so I thought it was a yeast infection so I went to the doctor & found out I had trich. They prescribed me 4 pills to take at once & then I went to sleep. When I woke up I didn't have no more discharge & the itching went away. The medicine is really nasty. I found to take it with milk was better. Over 12 hours later I started getting nauseous. I almost got sick but haven't."
