Welcome to SR! Lots of great advice above. The first few days are the hardest, but stick close to hear, and post before drinking. I had to plan out every minute of the first few days/weeks.
You will start to feel better physically, and then emotionally. I am just about 8 months on and it is much easier than it was. The thoughts of drinking do not pop into my mind often, and when they do I am able to play the tape through and think about how I would feel the next day.
Stick around here, read, a d post. You can do this!!!
