I've looked and as far as I can see so far, there are no mods that require you to sleep without there being an added requirement to eat and drink. I tend not to use the needs mods at the moment because they all involve some micro managing and kind of break immersion whilst playing, going into the menu etc. I'd like there to be a mod however where you have to sleep otherwise you receive penalties, reduced health, reduced carry weight, those kind of things. I'm not sure how hard it would be to make a mod like this, probably pretty difficult for me but for someone with experience in this it's probably quite easy, but I don't know! Thanks in advance if anybody actually makes this.
