I need help finding the name of this old computer game!?

I played this game probably over 10 years ago. The name of the main character was Gram and I can't even remember what the purpose of the game was but I do remember that you had to find and drink water to stay alive. When "Gram" would drink the water he would say something like this: Aahhh, water, nectar of the Gods, I will drink and soothe.
