I guess it makes sense why you're getting such intense urges right now, si is also an addiction and I guess now that you're trying to cut out the drink you're looking to something else to help manage how you feel.

Try to stay strong, these urges will settle in time and beccome easier to handle. Have you ever tried flicking elastic bands on your wrist or squeezing ice cubes etc? Might help to calm things a bit without actually giving in to si
