Good morning OP. I did try AA - they were welcoming and friendly but it wasn't for me. At first because there were people there who I viewed as "worse than me" and developed a mindset along the lines of "well, I can't be an alcoholic because I'm not as bad as THAT poor s#d", which was highly unhelpful (and not true). I approached my GP for help and was referred to an addiction recovery service called Inclusion, where I had a support worker and attended SMART recovery sessions (Self-Help Addiction Recovery | UK Smart Recovery), which I did find helpful. They also offered online sessions. Inclusion certainly helped me a great deal; I can't speak highly enough of them. Inclusion website: Drug & Alcohol Services - Inclusion - hopefully they might have a service in your area to help, or they may be able to advise if you reach out to them.
GP support is vital if you want to regain your driving licence. You will need to demonstrate abstinence, including a recorded "date of last drink" with your GP and, if required as a result of your conviction, results of liver function tests (LFTs) - I'm sorry, I can't really advise on those as I gave up my licence voluntarily without ever being stopped, so those tests were not required in my case.
Beware in dealing with the DVLA - anything innocently said such as "I only have a sherry with Christmas dinner" will be enough to prevent you getting your licence back for another 6 to 12 months, even if you never even look at a bottle for the other 364 days of the year. Despite the fact that I don't have even so much as a single point for speeding on my clean licence, and every proof that my licence was surrendered voluntarily and at nobody's request, I am classed in with the HROs (High Risk Offenders) and must submit myself to annual reports, medicals and blood tests. It is humiliating. I have had to stand in line for medicals with people who have committed serious drink-driving offences (rightly subject to scrutiny). And there is one guy who has served actual prison time for a third(!) DD conviction (now clean and sober and very generous in his support of others), who now no longer has to subject himself to the same annual scrutiny that I have to endure. I understand that I brought this on myself with my drinking. But I won't lie that there are times when I regret "doing the honest and decent thing" and surrendering my licence when I knew I had problems. I should have just put it in a drawer until I was better. But I could not have lived with myself if I had driven drunk and caused harm to others.
SMART recovery and the support was very helpful. But ultimately I was successful because I wanted to be. I knew I was killing myself, the effects were becoming more and more obvious, along with the impacts on my lasting health future. I was ashamed of myself and the miserable existence that I was living and condemning my dog to live as well. I wanted sobriety. So, I engaged properly with the support on offer, faced the issues and somehow got through it.
I found Clare Pooley's book "The Sober Diaries" extremely helpful and, later, also "The Unexpected Joy of Being Sober" by Catherine Gray. The One for the Road podcast by Sober Dave was also good, though I am not really a podcast person. I now use the I Am Sober app on my phone (it's free). I took each day as it came (a cliche but it works) and celebrated each sober morning internally, and each returning sober feeling. I began to look at alcohol like a poison, slowly killing me. You wouldn't put alcohol into your car's petrol tank - it would destroy the engine. It's the same for humans. I did it for myself, because I needed/wanted to. I hated being reliant on the bus and feeling like sh#t. But mostly I did it for the dog. They deserved better than the me I was.
At some point, I am sorry to say, you have to make the choice of which one you want more: a driving licence or drinking? Because - especially with your conviction and nearly-expired ban - you can't have both. Is it worth not being able to drive for another 12 months because you want a few glasses of wine of an evening? After a number of years, I made the choice that the booze was not worth it. This thread helped: The reality of the end | Mumsnet (be warned - it's grim reading. But it's what awaits us all in the end if we don't sort ourselves out). There are other helpful threads, here on MN and elsewhere.
I won't lie - it was not easy. At times it was very hard indeed. But I can absolutely guarantee you that it is worth it.
Good luck to you, whatever you decide. x
