Dealing with food craving

During sleeping I experience strong food urges.. luckily I am most of the time aware of these acts but I still usually eat something but less (which is an accomplishment). It happened today again and before eating I rehearsed internally "I am the owner of my actions,heir to my actions..." which switched my focus more to a long term perspective because I knew that I would perpetuate a craving so I better tolerate the pain now then to go the old pathway which would maintain the kamma.. Now any recommendations what I could do? I think I have to meditate more on the disadvantages / short nature of food and even on the kamma thing (which is important anyways to keep in mind). Suggestions?
