I'm currently on metronidazole for the 2nd time in a few months due to a wisdom tooth infection and feeling rough as. I just want to go to sleep at my desk, I permanently feel really nauseous and the metallic taste is foul. We're going to be TTC soon and it's making me worry about how I'll cope with morning sickness. For those who've had both, did you find morning sickness as bad as metronidazole? This is vile!
