Sleep Debt

Sleep Debt makes sleep matter again.

In vanilla Minecraft, sleep is mostly just a way to skip the night. This mod turns it into a small survival system: stay awake too long, and your character starts to feel it. Push through the exhaustion, use caffeine to keep going, hunt phantoms for better rewards, or actually sleep and wake up refreshed.

Simple idea. Better gameplay loop.

What does it add?

Sleep Debt adds a lightweight fatigue system built around insomnia, caffeine, beds, and phantoms.

If you avoid sleeping for too long, your sleep debt starts building up. The longer you stay awake, the worse the fatigue becomes. You can temporarily suppress it with coffee or an energy drink, but stimulants do not replace real sleep.

Eventually, you either rest properly or deal with the consequences.

Main features

Sleep debt system

Staying awake for too long causes fatigue to build up over time.

The system is designed to feel natural in survival gameplay. It does not constantly punish you for missing one night, but if you keep ignoring sleep, the effects become harder to deal with.

Coffee

Coffee gives you a short burst of energy and temporarily suppresses sleep debt symptoms.

Coffee effects:

Speed I
Haste II
3 minutes duration
Temporarily suppresses sleepiness

Coffee is crafted using roasted cocoa beans and a water bottle, giving cocoa beans a new practical use.

Energy Drink

Energy Drink is stronger in the moment, but worse afterward.

It can help when you really need to keep moving, mining, or fighting, but once the effect ends, you crash.

After the Energy Drink ends:

Slowness II for 60 seconds
Mining Fatigue II for 60 seconds
You cannot suppress sleepiness again for 5 minutes

It is useful, but it is not free power.

Well Rested bonus

Sleeping in a bed rewards you with a Well Rested bonus in the morning.

The goal is simple: sleeping should feel like a good decision, not just a skipped night.

Better phantom rewards

Phantoms become more than just annoying flying problems.

If you are sleep-deprived, phantoms drop extra membranes. This turns insomnia into a risk-reward choice: staying awake is dangerous, but it can also be useful if you are willing to deal with the consequences.

Golden apples clear fatigue

Golden apples can remove sleep debt completely.

This gives them another emergency survival use outside of combat and makes them valuable when you are far from a bed or stuck in a bad situation.
