Congrats!
Your wife might be a little scared if it's been a long time since she's known the sober you. It will be a time of discovery for both of you.
Be kind and you'll both adjust better, and helps to avoid triggering either of you.
Simple kindness goes a long way in a marriage, any marriage!
You might want to tell her over the phone that you aren't drinking, and give her a heads up so that she can start adjusting too.
Just a thought-tailor it to your marriage.
