trichomoniasis
"I had really severe trich symptoms and this cleared it up in about a week. I took the single dose of 4 pills in one day on a full stomach around noon. By 9pm I was throwing up nearly every hour on the hour for 5 hours and I was nauseous all the next day. I also had discolored urine and the pill tastes awful. BUT this antibiotic worked incredibly. The doctor said the vomiting wouldn't affect my recovery because it'd been long enough since I took the pills."
