Tinidazole
"I've been on 500 mg twice a day for two days. I'm supposed to take it for three more days. SEVERE side effects. I have extreme weakness, numbness in my left hand/arm, body aches, now severe pelvic pain, which I'm hoping is just a Yeast Infection, nausea, food tastes weird, I can only drink water with lemon because it makes the water taste metallic, severe fatigue. 
My doctor has been trying everything for Bacterial Vaginitis on and off for the past year, and especially the past 6 months. I know this will work (as Flagyl did in the past), I'm just hoping the side effects go away."
