Stim-ply Amazing (achievement)

 is an achievement/trophy in Fallout: New Vegas which is awarded for successfully healing 10,000 points of damage with stimpaks.

Strategies
An extremely easy way to get this challenge/achievement is buying/getting about 200 stimpaks (or less, depending on your medicine skill) and then diving into a lake. You will start losing health after running out of oxygen. Then, use the stimpaks in order to heal and get the achievement.

To do this with fewer stimpaks, don the Followers lab coat, pop some mentats, have Arcade Gannon in your party and read Today's Physician. This will boost your medicine skill substantially and greatly reduce the number of stimpaks required.
