I like going for walks. They require no mental effort, but provide some physical release as well as I get to get outside of whatever 'fishbowl' I was stewing in.
I also like to remember that it was my past drinking that is causing my current cravings. My cravings are a sign that I am healing, so I can stop and think, "yep, a craving is exactly what an alcohol who has quit drinking is supposed to be feeling."
