Welcome and congratulations on day three.
You're in a great place here and there's no reason why you can't start this exciting new part of your life.
A lot of us here can relate to not being able to stop at one drink, and that's the nature of the beast. It's nothing to be ashamed of as you're three days in already! Definitely check out the forum and maybe build up a recovery plan for when you get cravings and just day to day maintenance. I like to read and I go to AA meetings :-)
