Metronidazole & Alcohol?

[QforDoctor]

I'm taking antibiotics, including Metronidazole 500mg for h.pylori. I was at my sister's wedding last night and took 2 glasses of bubbly to toast with the guests, and then switched to water all night (being under the impression that antibiotics just worsen the impact of the alcohol so this is why you shouldn't drink). About 6-7 hours later I started feeling really unwell (nausea, frequent washroom trips, flushed skin).. I looked up my meds and realized that I goofed with the Metronidazole as there are other reasons why it shouldn't be taken with alcohol because of the side effects it can have. I have taken my dose this morning a little later than usual from fear the symptoms wouldn't subside. I'm just wondering, since I'm mid-treatment, is it safe to continue taking the antibiotic combo, especially Metronidazole, or is taking it after even just a little bit of alcohol going to send me to the hospital because of compounded effects? Thanks
