I'm in the process of writing the penalty/bonus effects (2 down, 9 to go, mostly copy/paste.) After that its time for debugging and filling out the nutrition info for foods, then I should be able to release.
Imp-
This is only tangentially related to this mod, but hear me out. I was thinking that considering the history of realism mods with Oblivion that there may be a value in having a core esm for managing stat adjustments and other settings.
The issue that came up with Oblivion was that there turned out to be several different approaches to penalizing a character, so much so that if say a hunger mod used method A and then a sleep mod used method B that they would not play well together and at times would even upset other types of mods like leveling mods. Mostly this had to do with the use of player.setav instead of player.modav. Still those of us who used a lot of different realism mods over the last 4 or so years know that even if player.modav is used (differently) by several mods that they still don't articulate right and that stat damage was a near constant thing to watch for.
If, however, there was one controlling plugin that was designed to manage all the bonuses and penalties for the character (and NPCs) and did this in a uniform manner then there may be less of a chance of them stepping on each others toes and interfering with each other. This way (with a controlling main plugin that managed only this aspect) then one could build extensions on the theme: Hunger thirst, new food mods, hypothermia, sleep mods, etc. ... all without the need to cover every base from the start.
For Oblivion Tejon made http://tes.nexusmods.com/downloads/file.php?id=41005 which approaches this idea in that it brings under control all the factors of a characters growth. It was made mostly for character advancement mods - with the idea of making all the variables of a character open to manipulated by a central control.
I know I don't have the head or the know how to pull that kind of thing off. In fact my head may be mush in even thinking this is a any kind of useable idea, but I thought I'd put it out there.
[edit]
I always use COBL with Oblivion - but COBL hunger is not a mod I would recommend.
But to expand on the idea. A core realism mod that could handle cataloging food, drink, and alchemy effects and then implement bonuses and consequences.
