Of course you are: Yes, that's what makes dieting hard. You can try different things to help this: eating smaller portions more frequently, drinking a glass of water, low calorie snacks, or taking a little walk. Your body will adjust and the hunger pangs will improve. Most cravings last 5-10 minutes and then go away, whether you give in to them or not.
