Update 9/20/23: I fixed it. The damage bug appears to be no more. Please download the latest version. Delete the old version entirely and replace it with the new one. 

UDPATE 2023: I've gotten a few very polite requests to unhide this mod, so I'm doing just that. I was never able to replicate the bug people were reporting despite literal hundreds of hours of gameplay with the mod installed. So please be aware that some people have reported stimpacks damaging them when they heal with this mod installed. Use it at your own risk. 

Does it bother you how your character just crams needles into his/her chest without so much as an "ow!" This simple esp makes it so that when you use a stimpack, you take 0 damage, your character makes says one of his/her "Pain" lines, and then the stimpack does it's thing. This should work for every npc in the game as well as the player.

This mod is beyond simple, contains no scripts, and adds a single effect to all the stimpacks in the game. I would describe it as bbarely noticible, but immersive at the best of times. 

I've not been able to do much testing, but it seems to work fine on my end. Let me know if you have any issues, and if you any ideas on how to improve it.

Most likely incompatible with any mod that edits stimpacks, but let me know if you find anything and I can try to create a compatibility patch.
