Upward---I am sorry to here about your situation. I am glad that you are quitting. You may want to consult you primary care physician to help you through withdrawls....depending on your usage.
A word of advice. Do this for you. I do not know how long you have been drinking or having marital issues because of it. If this has been going on for a while... It is not going to be a magic switch. Your wife is more than likely not going to give you a pass because you have quit. you are going to have to do it for you.Heck I told my wife I was quitting a hundred times. I am sober a year and the trust is just now starting to come back into our relationship. She sees how I am living and not just idle promises in the night. Is it worth the time, effort and struggle. Every Second.
I wish you success on your journey.
Peace
Dave
