I was treated foe chlamydia around 2 weeks ago, was a weeks course of antibiotics 2 to be taken daily yet I vomited 2 tablets back up does that mater?

Probably not. Your 6 days of antibiotics should be sufficient. This presumes that your sexual partner(s) have been treated as well, or you can contract it again. You should be rechecked to assure that it is cleared.
