I was just thinking if it is possible to make a mod that forces you to drink and sleep and have warm clothes and eat and also it takes longer to eat things.
And also maybe make cyrodiil larger and make the game even more cozy.

this is just a thing ive been thinking about for some days.

Whilst I don't use them myself, there are definitely Mods that add Hunger/Thirst to the Game, and some I believe that make you need sleep
Note: I do not use any of these myself, so do not know if these are the "Must Have" Realism Mods; someone else may know if there are newer/better Mods available, these just come from a quick Tes-Nexus Search.
