Inspired by the Many A True Nerd's series of YOLO runs. All forms of healing are disabled (for player only).

The effect of all of these are disabled:

 - Health potions (all three types: Restore, Fortify, and Fortify Regeneration). You can still get XP for making them though.
 - Enchantments that fortify health, regeneration rate, or absorb health.
 - Healing spells. But you can still heal others, in case you want to have followers.
 - Natural health regeneration.
 - The health top-up when you level up or sleep. (works with or without Survival mode).
 - Ebony Blade artifact, Blade of Woe.
 - Argonian's Histskin ability.

YOLO mode is disabled by default, it has to be enabled through MCM.
Disease cures (shrine and potion) are not modified, unlike FO4 they do not go away on their own.
Upon leveling up, your health increase is proportional to your total health. If you've lost 50% of your health, you'll receive only 5 points instead of the usual 10.

Note about survival
There's a known issue in Survival mode where you can heal up by getting cold first and then getting to a source of warmth. Between that, and the constant damage from freezing waters I don't recommend combining this with survival mode. But I'm not your father, you don't have to listen to me.

Compatibility
Potential incompatibility with mods that change when you level up. Everything else uses the magic of Keyword Item Distributor thus should be compatible with everything, including mods that add or modify races, spells, potions, etc. If you do encounter something that does heal you, please report it.

ESL-flagged so it does not take up a slot in your load order.
