Not really connected to this problem, but for technical reference part I here http://www.gamesas.com/index.php?/topic/1234691-necessities-of-morrowind-hunger-bug/ . The setup is the same, Morrowind + Tribunal + Bloodmoon + mods according to Morrowind Expanded guide, NoM v. 3.02 . This time though my character simply won't start being hungry. No lunch/dinner time approaching messages and no hunger penalties appear. Thirst penalties and water consumption is without problems. I'm only using manual eating but for testing purposes tried automatic mode - it works, i.e. character eats at regular intervals, although no visible effects ensue (obviously, since there are no hunger penalties to be removed). I believe it all started when I spent about 24 ingame hours chain-training so perhaps I sort of broke the start of hunger scripts. Reconfiguring NoM doesn't help, which is somewhat understandable since hunger scripts can't be configured from NoM menu and therefore can't be reset. I'm thinking maybe there's a way to reset or restart those scripts through the console? Taddeus, an input from you will be highly appreciated since you've helped me wonderfully the first time (which, ironically, if you recall, did not remove hunger penalties after eating).

Uhm, it seems that all your problems come from the same NoM script. I think the script got struck for some reason and can't complete its course.
Try this in the console: "StopScript NOM_hunger_penalties". And then wait for the next lunch/dinner hour. Hopefully it will solve the problem.
