I agree with @ShyMaryEllen. I honestly do NOT wish to cause alarm or scare-monger in any way. But it's a question worth asking. The last thing you want is any form of driving check where a GP mention of alcohol issues/abuse drifts into the DVLA's orbit.
They have been merciless with me over the last five years - and I have never been stopped nor garnered even a single point for speeding or tail-light infringements on my licence ever since I started driving in 1998. A voluntary self-referral and temporary surrendering of my licence in 2017 has resulted in misery ever since. There are literally people who have served time in prison (I know, I've had to line up for medicals with them) for DWI offences (rightly - they deserved to be punished) who do not have to continue with the yearly scrutiny that I have to. One was a guy who'd served a custodial sentence following his third (!) DWI conviction - he is clean now - he had to do the annual checks for three years in a row before being given his full licence back. This will be my fourth year. I'm classed with the HROs, despite the fact that I've never driven under the influence nor so much as stolen a foam banana off the pick'n'mix. Gits.
Again - I'm not wanting to cause fear or even mild alarm. But make sure it's recorded in your notes that you are sober and the date you last had an issue. It sounds like you've already covered that though @WendyWagon, hopefully that'll be OK.
Apologies again for having a moan. I brought my situation on myself, I know. But do beware - the DVLA are not medical people but have the say over your fitness to drive with only scant regard to evidence. I know of others who passed all the blood and urine tests, received exemplary reports of sobriety and health from their GP, but have had their licence refused by the DVLA because they accidentally wrote a single digit incorrectly on the "date of last drink" box so it didn't tally with one on a different form - thus they were deemed "deliberately deceitful" (though I think their licence was successfully reinstated on appeal) and it is soul-destroying trying to get through to them.
Sorry, sorry sorry. I don't mean to sound miserable and bitter. 😳
Normal service will be resumed shortly, once I've had a cuddle off young Sidney. 😉
Strength and love, as ever. x
