I have a zero tollerance policy for alcohol when I know I will be driving the same day or early the next.
It is far easier to just say “no” from the start than trying to calculate and estimate what would be an acceptable ammount at what time to be able to drive.
Yesterday when I drove home from NYE at my parents, road conditions were terrible, it snowed, the council had not cleared it as I drove home (understandable), and I felt my car loose grip a few times. On roads with a limit of 70km/h I drove 35-40, and on a road with a limit of 90km/h you could not drive any faster than 60, I have excellent winter tyers, but it took all my stone sober concentration to get home safely, if I had had any alcohol, trying to drive home would have been utterly reckless, to be fair, it was borderline reckless when as I drove home sober, but it was doable.
Why is it a “yikes” situation to make 100% sure that you have zero alcohol in you when driving?
As for drinking, it is a very small part of me, while I have an extensive collection if spirits, I hardly ever drink.
