Welcome. As mentioned before, this is a great place to be for support and information.
I agree with Sugarbear, you really need a solid plan for the first week. You have to try and change your normal routine as much as possible to avoid falling into the same old routine which included wine every night. What can you do during the 5-8 hour? How will you handle any cravings that may pop up? What support system do you have? Are there support groups you can attend?
It's all about change! The first change that has to happen is not drinking. The rest will come in time.
Glad you are here!
