bacterial vaginitis
"This is my first time taking metronidazole and first time getting BV. I am supposed to take 2 tablets a day for a week (500 mg). The first few days were fine, I noticed I was beginning to get tired though. The fishy odor went away  by like day 3. By day 4-5, I was beginning to get more symptoms like headaches, dark urine (even though I drink a lot of water), minor upset stomach, trouble focusing, and irritability. By day 6, I was lightheaded, confused, couldn't focus at all, and nausea on top of all the previous symptoms I mentioned. I am not completing this prescription with 2 pills left. I also am a healthy 4'10", 100 lbs, and 21 years old female who only takes medication when it's a last resort."
