It's pretty basic. I want a mod that will let me experience the hardcoe mode features (sleep, hydration, food, ammo weight), without the 'companions die instead of going unconscious'. Yeah, so I am not into babysitting them or missing out on their content.

Has anyone already made such a tweak (if not - pretty please)?
