Congratulations on your first week!
I think you have a good strategy. I initially stopped drinking in August, and about a month later, I went to a wedding with an open bar. I didn't indulge like I normally would have, but I still felt ashamed of unraveling all of my hard work. Maybe think about how successful you've been over the past week and how you'd feel if you had to redo it? That first week is so difficult (or at least it was for me, mentally). Honestly, who wants to go through that again?
I'm glad you have the support of your wife. This might be just the opportunity to see how much you can enjoy yourself without alcohol.
