Insomnia (2.5e Flaw)
From D&D Wiki
If you have Insomnia, then it means that you haven't slept in a while. You are very tired, and will be grumpy... You won't really want to do anything at all, except try to sleep. This will be very hard to do though.
Will be very tired. -1 to attack "to hit" rolls. Takes double the time to cast spells.
Act Grumpy as if you haven't slept in weeks.
