This is the main framework for Better Sleep Autonomy, which simply forces Sims who are on their home lot and not in bladder or hunger distress to go to bed around midnight, regardless of their energy motive. They'll continue to want to sleep for about 7 hours (if they're able to*) but the call to bed doesn't cancel other actions and can be easily overwritten by the player, so it shouldn't be intrusive or bothersome. If a Sim gets up to use the toilet and is still in their "sleep window", they'll go back to bed afterwards. Other modules expand upon this and create different sleeping behaviours depending on a Sim's traits, moods, and lifeskills.

Expansion module for Better Sleep Autonomy. This mod changes when Sims autonomously get out of bed. Without mods, Sims will wake up 2 hours after their energy is full or an hour or two before work or school, whichever occurs earlier. With this mod, they'll instead sleep at least 7 hours* from the time they go to bed. (*Unless work or school comes sooner.) Their wake up time is influenced by their job or school. Average Sims will always wake up at least one hour before they need to go to work or school. If their energy is filled, they'll wake up two hours before work or school. Unemployed Sims will wake up at 8AM. Lazy Sims will sleep an additional 4 hours after their energy motive is full. This behaviour is further expanded upon if used in combination with the Morning & Night module. Morning Sims will wake up around 5AM and Night Owls will wake up no earlier than 12PM*. (*Unless forced to wake up for work or school.) If used with the Life Skills module, a Sim's responsibility will affect their wake up time in relation to when they need to be at work or school. Unemployed Sims are free to sleep as long as their sleep cycle dictates.

Expansion module for Better Sleep Autonomy. I've always thought it was stupid that the reward traits "Morning Sim" and "Night Owl" had no effects on a Sim's behaviour. It was especially annoying to me that Night Owls wanted to sleep fairly early during the night even if their energy motive wasn't low. This mod causes Sims with "Morning Sim" or "Night Owl" to go to bed at different times. Morning Sims will go to bed after 9PM and Night Owls will go to bed after 3AM. A Sim's career will affect the timing. A Night Owl on a night-shift job will stay up until about 6AM, whereas a Night Owl with a typical daytime job (or unemployed) will go to bed around 3AM.

Expansion module for Better Sleep Autonomy . This mod causes a Sim's moods to affect their sleeping behaviour in the following ways : --Children and Childish Sims won't autonomously sleep when playful, energized, or scared. --Teens, Perfectionists, and Outgoing Sims won't autonomously sleep when embarrassed. --Children, Teens, and Hot-Headed Sims won't autonomously sleep when angry. --Adults, Perfectionists, and Ambitious Sims won't autonomously sleep when stressed. --Genius Sims won't autonomously sleep when focused. --Creative Sims won't autonomously sleep when inspired. --Romantic Sims won't autonomously sleep when flirty. --Gloomy Sims won't autonomously sleep when sad. --Active Sims won't autonomously sleep when energized. If used in combination with Life Skills, a Sim's responsibility and emotional control will further influence how much effect moods have on individual Sims.

Expansion module for Better Sleep Autonomy. This mod causes a Sim's responsibility and emotional control to affect their sleeping behaviour. Doesn't do much on its own, but when used in combination with Wake Up and/or Moods, will have the following effects : --Irresponsible Sims won't conform to a schedule. They'll go to bed whenever they like and wake up whenever their energy is full. They'll only wake up for work/school at the very last minute. (Basically, irresponsible Sims have the default Sims 4 sleeping behaviour, except that they won't sleep for an additional 2 hours after their energy is full.) --Responsible Sims will always wake up at least 2 hours before work/school, regardless of their energy motive. --(If using with Moods module) Emotionally Controlled Sims will be able to autonomously sleep regardless of their mood. --(If using with Moods module) Sims with Uncontrolled Emotions will find it more difficult to fall asleep and won't autonomously sleep if they're angry, sad, stressed, embarrassed, energized, or focused. (They can still be commanded to sleep.) Teens and Young Adults with poor emotional control will also not want to sleep when feeling flirty. Goofballs with poor emotional control won't want to sleep when feeling playful. Young Adults, Adults, and Elders are affected based on their traits and Children and Teens are affected based on their current character values.
