Welcome BrightStarr! Good for you for tackling this issue now--I wish I had stopped drinking when I was 23! Many of us can attest to the progressive nature . . not pretty.
As for tips for your first week--
Eat regularly. Stay hydrated. Remember that cravings WILL pass. Tell yourself "no" and mean it. Stay close to SR and reach out for support whenever you need to. Change your routine a bit. Relish your hangover-free mornings.
Best of luck to you!
