Alcohol 24 hours after metronidazole?

I was prescribed metronidazole for BV. I finished my dose last night, so it has been almost 24 hours. Can I have a beer tonight? or should I play it safe and not have a drink? I did well on an exam today and want to celebrate :D but am also fine just having a coke, just curious because I was told NOT to drink. F24, 5'3 and 150 lbs.
