Those thoughts are going to come, but they are just thoughts.
I have a lot of thoughts every day that I don't act on. I know you can do this. Give it a couple months and see if you don't feel like an amazingly different and better person.
You've made the decision. Now just ride out those thoughts and anxieties and in no time there will be a new amazing life for you.
I kept repeating to myself, "I don't drink, no matter what."
