trichomoniasis
"I found out I had trich within days of being infected. I was prescribed twice daily for 7 days. While my partner, he was prescribed the same, but the 4 pills at one time. We saw different doctors and his lab work hasn't confirmed trich, but since I tested positive - they treated him as if he had it as well.

Also was prescribed the miracle pill for a yeast infection, if the metro causes one. 

Terrible metallic taste - I can't imagine 4 pills in one day. 

Will update with the effectiveness for both he and I."
