Bryan,
You will have a little more than 2 weeks before your
drink driving medical test after your birthday. I've heard people who have refrained from alcohol consumption 3 weeks prior to their medical test fail their liver function test. You are so close to getting back your licence and it would be a shame to take such a risk after waiting for 4 years.
Therefore it is best if you abstain from drinking on your birthday to give you the best chances of passing the drink drive medical test. You later celebrate both your birthday and getting back your licence - bearing in mind not to drink drive though!
