...And Not a Drop to Drink

...And Not a drop to Drink is a challenge in Fallout: New Vegas.

Challenge requirements
The Courier must drink 100 water items.

Effects
Grants 100 XP and the Camel of the Mojave perk upon completion.

Behind the scenes
The name of this challenge is based on a verse from the poem, "Rime of the Ancient Mariner," written by Samuel Taylor Coleridge: "Water, water, everywhere, and all the boards did shrink; Water, water, everywhere, nor any drop to drink."

Bugs

 * The number of times water drunk may show as zero on the Pip-Boy 3000, no matter how many times the character drinks. This is true in both regular and hardcore modes.
 * The game may not give a notification that the player has hit a milestone in the challenge, regardless of reporting every drink of water or not.
