I personally did not have a lot of cravings in the beginning, but I know others have had a very hard time in the beginning. Are you actually hungry or is it just your mind craving food because you can't have it? Either way, it never hurts to talk to your doctor. A large part of the changes you'll go through with WLS is adjusting your relationship with food to be one of healthy balance. That mental adjustment does not happen overnight, regardless of what physical changes came about through surgery. I really would not suggest eating actual food though, as it will most likely make you sick so soon.
