If you don’t drink, there is no such time as “after [you]'ve been drinking,” so you’ve never driven during it.
I drink occasionally, but I don’t drive
You don’t think so? Few people will admit to driving drunk (self-styled rebels might, or people who figured that it’s ok because no one got hurt, or very naïve people) but if it’s phrased like that I can easily see people admitting to driving buzzed, or saying “yes” because the question doesn’t make that distinction.
