Yep, like me said.. there's an acronym thrown around to look out for (HALT, Hungry Angry Lonely Tired), those times when 'cravings' or whatever you want to call them are sometimes the strongest.
Do anything BUT drink. I like to run to the gym.. or make sure I'm well fed.. call someone I had neglected in my drunken past.. get into a good recovery book.. go to a meeting. anything but drink.. and then it passes as long as you don't obsess and invite the thoughts to stay.. and you continue your day.
It's work! Meetings, reading, counseling, phone calls, exercise, walks outside (even just around the block.. something about being in fresh air and noticing all the other 'life' going on around me was very helpful to readjust my self obsession for a bit) all helped for me.
