Yes, I think this is par for the course for a lot of us Steve. This subject is discussed here quite frequently but there can really be a lot of reasons for it. If you are concerned that it's affecting your general health speak with your doctor of course. Some theorize that it's your body trying to make up for the lost carbs that you were consuming when drinking, especially if you drank a lot of beer which is loaded with empty carbs. Others would suggest that it's a "replacement' addiction. But just like alcoholism, it's usually more productive to try and address the things you can address today rather than trying to search for all the "why" answers.
