Constant water drinking

I have the same problem and my sim will drink water instead of eating when hungry. It annoys me that the sim will drink water from the refrigerator instead of grabbing leftovers.

I think this is a bug that needs to be fixed, but even if it is not, I wish there was a way we could turn this off without installing mods. Every time I have ever used mods in the game, it gets so buggy I cannot even play until I take them out.
