Insomniac is a Fatal Flaw featured in The Sims Medieval.

Sims with the Insomniac Fatal Flaw have difficulty falling asleep when they want to. Unfortunately, this means that they are so tired during the day that they will sometimes fall asleep when they decidedly do NOT want to.


  • Sims wake up frequently at night and gain the "Can't Sleep" buff, which prevents them from sleeping or napping at all for the duration of the buff, no matter how tired they are.
  • Insomniacs receive considerably less sleep than other Sims, and thus will often fall asleep at inappropriate times during the day to compensate for the sleep they lost.

Related MoodletsEdit

  • "Can't Sleep" (-5 focus for 3 hours)
  • "Well-Rested" lasts for 8 hours instead of 10
