You have great difficulty achieving a full and restful sleep.
Benefit: In order to get a full night of rest you must succeed at a DC 15 Fortitude save. If you are sleeping and a disturbance wakes you during the night, you must make an additional save (at the same DC) to return to sleep. If you fail the Fortitude save you are fatigued when you rise in the morning. If you are fatigued when you try to sleep, you gain a +2 bonus on your save. If you are exhausted, you gain a +6 bonus. Comfortable conditions, such as those found in most inns, grant you a +4 bonus on this save. Poor conditions, such as sleeping on the ground or in armor, give you a -4 penalty on this save. Even if you sleep poorly, you may prepare arcane spells as normal after 8 hours of fitful rest.
