Bawls Bottle

Bawls Guarana (named Bawls bottle in-game) is a consumable item in Fallout: Brotherhood of Steel.

Background
Both in the game and in real life, Bawls Guarana started as the brainchild of a 20-year-old college graduate named Hoby Buppert, who in 1997 was looking for an alternative to coffee. As part of a class project, he came up with a carbonated and non-alcoholic beverage made with guarana, a highly-caffeinated berry native to the Amazonian rainforest. The drink is named "Bawls" for the caffeinated "bounce" it gives you, as it contains a natural form of caffeine nearly three times stronger than that found in traditional sodas. The name also plays on the slang term for being "bold and daring".

Looking for a place to settle, Hoby Buppert chooses Texas, a quiet place conducive to the growth of Guarana. The company only markets its drinks only in Texas, never looking to expand because of the dominance of the market leader, the Nuka-Cola Corporation. Nonetheless, before the Great War, Bawls Guarana concluded a lucrative contract with Vault-Tec, which wanted to build the Secret Vault in Texas. They sponsored the construction in exchange for the exclusive right for only its drink to be allowed in the vault, at the expense of Nuka-Cola, which is absent from this region.

Characteristics
Despite advertising in Carbon, you can find Bawls bottles only in the Secret Vault, especially in the Bawls vending machine that contains 9 bottles (and 4 more if you destroy the machine). Each bottle will heal you 1/4 of your Hit Points until 2/5 with the skill First-Aid at maximum level.
