i shut that shit off using /gamerule doInsomnia = false
i fucking hate that entire mechanic
if i had my way, sleeping in a bed would do something else entirely such as:

1. Present the option to create a backup save of the world snapshotted to that moment
2. Restores satiety to the same level as your hunger bar but does not restore actual hunger
3. Gives a "rested" buff of health boost/absorption, luck, haste, and night vision that will last almost until noon in-game. bright eyed and bushy tailed!
4. perhaps all of the above.
