At this point, the challenge is a breeze. I don't even look at the other beverages in the fridge. Previously, water would be a last resort. I would drink the beer, then the soda, then the juice, then the milk. When all of that was gone i'd be forced to drink water.
I actually look forward to a nice glass of ice cold water. I've also been drinking sparkling mineral water and water with lemon and/or lime added. It helps change the pace and adds a little variety while technically still only drinking water.
