I have just released this. Hope that someone will find it useful :) Enjoy!
Immersive Food and Gear Improvements
This mod changes how food, drink and gear improvements work. Food and drink will last longer, but regenerate less HP ( both somewhat randomised) to simulate satiation, hydration and varied quality of food and drink. The duration of gear improvements will last a full in game day before they wear off, which makes them more realistic and useful.
