Hi Sue,
I agree w/ the others on how setting a date often results in unfortunate relapses. I can personally say that I've always failed when I told myself "one last time" "tomorrow I'll do it" and all the tomorrow's continue to pass with no success. Everyone is different though and I truly wish you the best
We will be here to support you and post as often as you can! There are plenty of resources available to you. AA is only one option. There are alternate programs that can help you as well. A lot of addicts find it very helpful to have face to face support, even if it's just seeing a therapist. I personally do not use anything except for SR and the support system I have built with several people on here who've become dear friends.
I am happy to hear that you want to get sober, you can do this!!
