Use motilium and probiotics.
Hello dear, welcome to Ask a doctor service. I read your query and here is my advice.
I think you should take metronidazole together with food in order to feel less nausea.
Also taking anti nausea drugs can be useful. I recommend you to use motilium(dromperidone) to stop nausea. Also it increases the intestinal transit and will help you feel less bloated.
You can take probiotics to help your intestinal flora to be reestablished. Take them at least two hours before or after metronidazole.
Hope I have answered the question.
Let me know if I can assist you further.
