Beer

Beer is an addictive drink found in Fallout 3 which increases player's Strength and Charisma by one while decreasing their Intelligence by one. The increase in Strength allows players to temporarily carry 10 pounds more.

Tactics

 * Drinking only beer and selling other drinks (Whiskey, Scotch, Wine, and Vodka) allows players to make the most of their items because the other drinks are worth more than beer.
 * Drink beer to increase your Carry Weight, then fast travel to a safe location with a marketplace (Megaton or Rivet City are good choices). By using Beer over stronger alcohols or Buffout you can prevent addiction.
