The body can heal from a lot as long as we stop poisoning it.
I know you can make it through this weekend. It's normal to have thoughts about drinking but they are only thoughts. We all have them. Just acknowledge the thought, like, "Hm, a drinking thought. Well, there you go," and then dismiss it with, "I don't drink."
The thoughts will come and go, just like all thoughts do. They don't mean anything. You probably have all kinds of thoughts every day that you don't act upon. The brain randomly throws stuff up all the time.
You don't have to act on the thoughts. They are just habits that you can break.
Keep it going.
