It is completely natural to crave sugar upon waking. A large reason behind this, is the drop in blood sugar that occurs while we are sleeping. The sweet taste of sugar is something that creates minor euphoria in our brains. So when you wake up in the morning, and you are feeling groggy and in need of a jolt to get the day started, the sweetness of sugar not only raises blood sugar, it also gives you a rush of euphoria. Of course, when you add sugar to caffeine in tea or coffee, this euphoria rush is even more intense. We are all creatures of habit, and this is also the main reason as to why you crave sugar upon waking up. Try not to go overboard on sugar early in the morning.]
