Stim-ply Amazing Achievement
Heal 10,000 points of damage with Stimpaks.
A much more reasonable achievement than the above Desert Survivalist, this is achieved either over time or in a fashion to the above given method. Visit a doctor to buy your stimpaks and wait when needed. A decent Medicine level and cash pile is suggested, and having Arcade as a companion can help speed this up. You can earn an infinite amount of Stimpaks if you follow the glitch mentioned in the "That Lucky Old Sun" level-glitch. See that achievement for more information.
