Fatigued
You can neither run nor charge, and you take a -1 penalty to your Armor Class, attack rolls, melee damage rolls, thrown weapon damage rolls that add Strength to damage, Reflex saving throws, initiative checks, and Strength- and Dexterity-based skill and ability checks. The amount of bulk you can carry without becoming encumbered is reduced by 1. If you are already fatigued and would gain the fatigued condition, you lose the fatigued condition and are exhausted for the total duration of all fatiguing effects. After 8 hours of complete rest, you are no longer fatigued.
