Metronidazole
"I knew for a while that something was off down there. I suspected BV, and went and asked my doctor for the antibiotic. I am VERY sensitive to most medications, which typically cause me intense nausea. So I was very nervous to try this stuff, especially after reading reviews. But I'm happy to say I've little to no side effects, aside from slight headache. However I did start with a very small dose, just to try it out. My doctor told me to take 500 mg (two pills) a day with food. But the first day, I only took half of a pill (about 125mg) just to see how it went down. No problems. Day two I took the full dose, no problems and BV symptoms are almost gone. Coated my pill in peanut butter as per my doctors suggestion, and have yet to taste it."
