Disabling insanity script?!

[pizzaclutch]

Hey guys.
I just started making my first custom story.

I am no pro at the scripting syntax nor do I realize the extent of what exactly I can do with the scripts.
I can figure it out.. but I am wondering if there is a way to disable insanity effects within my custom story.
I wonder this because I want my story to be exceptionally dark, with very minimal lighting; I do not want to have the player becoming insane and dropping to a crawl because of this fact.

I also wonder if it is possible to edit the intensity / brightness and / or radius of the light provided by a lantern. For my proposed idea of the map, I feel as if the lantern provides TOO much light for my liking.

Any thoughts? Thanks!
