Hi Soberforbaby. You have the same recent history as myself it seems. I was sober 11 months last year, drank for about four and have been sober again for six days now. My poison was wine however and perhaps not quite at the volume you have been consuming - which is nothing for me to be proud of, of course. I'm also an atheist and find AA (which I attended for several months) increasingly hard to take for many reasons, which I won't go into given the many AA members who come here.
On this occasion I have taken a different approach. I have a plan, I keep a journal (I won't go into details about those things), but crucially I have started counselling with an addiction specialist with the aim of exploring what underpins my addiction. I am finding this really helpful after only two sessions.
Is such a resource available in your part of the world - or something similar? There are also an increasing number of secular based group session available in the USA (sadly not here in the UK), SMART being one of them.
All the very best to you - good luck!
