I really hate that my sims are always trying to drink instead of proper sleep. I've tried to find mods to fix this, but haven't found anything at all. Do you know mod like this or at least the way to stop chars from killing themselves with caffeine?
I'm sorry if this is offtopic, I just don't know where else should I ask about this. (i built a freaking fence over the coffee machine and theyre still trying to reach it)

Should be fixable with Nraas Retuner. I haven't tried it but you should be able to set up times when it's "legal" to dink coffee, how "attractive" all that coffee drinking is and so on.
