Beer

 is a food item found in Fallout 3. It has an effect on your stats, but is addictive.

In Fallout 3, it adds +1 to your strength, which is another 10 pounds or so of items you can carry when Fast Traveling.

Tactics

 * It can be a good tactic to only drink beer and sell other drinks like Whiskey, Scotch, Wine, and espessialy Vodka (because it has more values then other drinks).
 * Drink beer to carry more stuff, then fast travel to a safe location with marketplaces (Megaton or Rivet City are good choices). By doing this, you can prevent addiction from stronger alcohols or from taking Buffout.
