Can you mix tramadol with metronidazole?

Yes, I am on 10 mg lortab every six hours for pain and for some reason--unrelated to the lortab, I tend to get bacterial vaginosis & yeast infections frequently so I take metronidazole a lot...Just came off of it, actually. But DO NOT drink ANYTHING with alcohol in it while taking the metronidazole or you will be sooo sick...Nausea & vomiting...No fun! Other than that, totally safe!! :)
