Metronidazole
"I never write reviews but I wanted to write one because I looked up the reviews on here and was so scared to take it because of everyone's horrible experience. I'm taking 500mg twice daily for 7 days of Metronidazole. The first day I was super light headed & had a hard time eating anything. I'm on day 3 and the symptoms are clearing up and the dizziness has gone away. It's still hard to eat anything and yes, I have a little insomnia. But nothing melatonin can't fix. The medications as far as I'm experiencing, really works. Don't let the side effects scare you away."
