I had my medical today as well!! The dr was not quite as nice as yours... no small talk at all and I travelled 140 miles to get an appointment as I had to wait until December for a local one.. I have not had a drink in 2.5 years. I quit completely after the offence in April 2019. The dr looked at me a little suspiciously which was not pleasant and then he had to ask me all of the questions about how often I drink etc. and I had to keep repeating "never" !
I am interested in the score issue. He did not tell me what score I had but I did answer yes to the questions "Has it ever caused you an issue in your relationship" as crashing a car drunk did cause me an issue... and yes to the question about "have you had an accident when drunk". It was no to everything else - he did not say if they would get in touch with my GP. I asked him and he said he did not know. I have nothing to hide if he does I am only bothered about more delays.
I will keep an eye on this to see when you hear anything in view of the fact we both had our medicals on the same day!!
I think that is always or was for me at least a thought of how the Dr doing the medical is/would be towards me/you I was at ease straight away, it certainly helped. The Dr I had said she didn't know how long the wait is at the moment asked If I did, I just said it's a bit of a lottery and she then was like it sound's like it is in a mess. As I say we now have essentially joined the waiting game, I'll keep an eye on any of your posts for updates as well.
Good luck and fingers crossed.
