The recommended dose of metronidazole (Flagyl) for treatment of trichomoniasis is a single 2 gram dose taken by mouth, not two separate 1 gram doses taken at different times.  The most common side effect following this is mild gastrointestinal upset.  Fewer than 1 in a thousand (and probably closer to 1 in 10,000) adults who consume alcohol within 24 hours of taking metronidazole will experience vomiting as an adverse effect of taking alcohol and the medication.

I hope this information is helpful.  EWH
