Put a gallons' worth of water in your fridge first thing in the morning ( or just before bed the night before) everyday. Aim to drink the whole thing everyday. A lot of us don't drink as much water as we think and you'll be amazed at how your cravings for snacks, and your appetite diminishes. Being well hydrated can help you feel less tired in the afternoons as well. Did you know that your body gives a lot of the same signals for thirst as it does hunger? It can be easy to "miss hear" them.
