This is a super simple mod that just makes Stimpaks work the same regardless of difficulty level. In Survival, Stimpaks now heal faster and for a shorter duration. I made it because I play on Survival with increased spawns, and I got tired of crouching in a corner waiting for my health to slowly tick up while a horde of enemies tried to end me. Surprisingly, I couldn't find a mod that did this on the Nexus.
