RainyEngland, welcome to the secular side of SR, you know, the one where we discuss and support alternatives to AA, just like it says on the box.
I'm glad you found us, and congratulations on your choice of sobriety. How do you feel about that Christmas party tomorrow? I found it helpful to have a plan in place, maybe a choice of non alcoholic beverage ahead of time, a place you can duck out to for a few minutes if things get too stressful to be comfortable, and even an alternate way to get home.
You can stay sober, anyone can, RainyEngland. You can do this if you choose to simply because you have the power and ability inside you already. Best to you.
