Personally, I think you get used to it after a while. Your body will crave more calories because that is what it is used too.
It does get easier, but dealing with the cravings can be tough.
Drinking water does help. Eating some low calorie food like carrot sticks, or low calorie yogurt can help as well.
2100 calories won't make you fat, if the 100 extra calories at 8PM can help you beat the cravings.
