A friend in pretty good shape overall mentioned a small snack issue. Sometimes the urge to snack is really a hydration issue.
One thing I like to do that can help with hydration while also appealing to a sweet tooth is to fill a Blender Bottle with water. I drop in an effervescent immune support tablet. I pour in a packet of EmergenC. Put the lid on and swirl till the tablet dissolves.
Usually I just chug it to give my stomach a full feeling. Sometimes I sip it over a twenty minute period to fill my mind. Either way it's good for you. Better than a normal snack.
