Hey glad your back, slipping can be part of the process. I would recommend that if you are not going to A.A. you should buy the book Allan Carr's Easy way to Control Alcohol, you need to condition yourself to not listen to the voice in your head that says go for it, you can have a few. It takes time, slowly it gets quieter. You can buy book online if you have an kindle or any other e-reader.
Make today the day you dust yourself off and start again! Best of luck my friend.
