OH!!!  And one other diet-related tip...  No food after 7:00 - or 8:00 - depending on your schedule.  This is really hard, but it does help your body's digestive system get on a schedule.  You wake up hungry, but that's actually a good thing.  It makes you eat breakfast, which, as they say, is the most important meal of the day.  If you must eat after 7:00 or 8:00, try to make it some protein - half(!) a container of yogurt, a spoonful of peanut butter.  It's amazing how satisfying that small amount of food can be.
