Which antibiotic you were prescribed?
Have you avoid sexual contacts until the treatment was completed?

Alcohol may increase the excretion rate or slow down the rate antibiotics are broken down.

antibiotics was Azithromycin.. Haven't touched anyone since. However i'm still a bit weary, Will alcohol have prevented the anti-biotics from running its full course?

Avoid sex for one week after treatment with azithromycin and make follow up with retesting for chlamydia.
As I wrote in my previous post,"Alcohol may increase the excretion rate or slow down the rate antibiotics are broken down", alcohol can affect the way the antibiotic is processed in body, leading to lower effect.

You can retest yourself 2 or 4 weeks after completed antibiotic therapy.

Thanks for your help, much appreciated.
