If the nurse told me verbally and not in writing, I wouldn't disclose it, and definitely not before I knew whether it was only a one-time thing.
I'm a conscientious and ethical person, but I've had enough experience being both screwed and overlooked by the system that I no longer blindly do everything they want (I'm from the US). If the practitioner doesn't report it and there's nothing in writing to force me to be accountable, then I'd take care of myself and not the system. If you research and find the med could end up in a restriction, then at worst you're prolonging the restriction if you get caught. I'd focus on my immediate and important needs rather than what the system wants. If they want it so bad, they need to work harder for it, and if they haven't set it up to get the information more easily for themselves, then I would wonder how big of a deal it really is. I'd also get informed by researching on the DVLA website, then weigh out all the risks and problems for disclosing vs. not disclosing.
You don't have to take my advice, just sharing what I would do. I won't be surprised if others disagree. Anyone can argue against my comment if desired, I've said my piece, others can say theirs, too. It's the OP's decision, and the OP wants input to make the best decision they can for themself, no different than planning or attempting ctb. I'm pro-choice on this subject, too.
