Eat more fiber during the day and you wont have crazy cravings as often or again.

A healthy snack... PB & Banana on a whole grain or whole wheat bread.
Yogurt + Oats mixed.
Black beans and Chips/Cheese (somewhat high in sodium)
Hot Cereal
High Fiber cereal with milk or alternative.
I like Kiwi's myself but bannnas, oranges, apples etc are nice too.
