Hi, Welcome to SR!!
For me personally I had a severe detox and would up getting a medications in the hospital that really helped me get through it. After I got out of the hospital I found that keeping myself busy with a recovery program helped tremendously. The absolute worst place for me to be was at home alone with nothing to do. Not allowing myself to get too hungry was really important also.
Cravings do pass but we can do a lot to fight them off. Calling a sober friend and talking is a great help. Sometimes getting busy with errands, shopping, taking a brisk walk can be a tremendous help. The mental aspects of addiction/alcoholism is extremely powerful and should not be underestimated. Engaging a recovery program is a very effective counter measure. I personally use AA and have found it to be very effective.
Good Luck!!
