(Guilty! I don't go for the Lucky Charms but a bowl of rice cereal with a bit of sugar always made a good snack for me. And yes I did usually wake up hungry. Just didn't know why)
Cereal
Lucky
Charms can be a great snack during the day. While it isn't very healthy, if you
are active through your day, you should be fine. However, when you eat sugary
cereals late at night, you are asking for trouble. Foods high in sugar will
mess up your blood sugar levels and most likely make it hard for you to sleep
throughout the night. You will wake up a few hours later feeling hungry and
possibly even with a headache. Instead of having a bowl of sugary cereal, try
having some oatmeal or other hot cereal that is low in sugar.
