Hi and welcome.
Sounds like drinking is causing some big problems in your life....one of the things you will here around here is "the yets"....as in, my drinking hasn't cost me anything big "yet" [ie your husband, an arrest for DUI, hurting yourself or someone else, etc]....I'm not that bad [don't drink as much/often/etc] "yet"....
If your life- or parts of it- are becoming unmanageable and you can't stop once you do start, when you drink, the idea of checking out AA is a good one. It sure has saved my life, among many others out there. And as Dee said- and so does your thread title "wanting to go Teetotal," btw- the only desire for "membership" is the desire to quit drinking. AA doesn't judge the how/why/how much that got you there- it welcomes everyone with a problem looking for a solution.
There's also lots of support here- check out the Newcomers Threads and "Class of Dec."
Good luck.
