Narrative:
After a circadian swap in my four day schedule I ended up calling in fatigued on the third day of a four day trip. I showed at xa:30; had a 12 hour duty day and was released at xm:00 on the first day. The second day was a 30 hour layover so I should have had enough time to prepare for my pre-dawn show on the third day. However; after trying to begin my sleep pattern early the previous evening but then waking up three hours later; then getting back to sleep three hours after that and getting up at for another pre-dawn departure it didn't seem my body received enough rest. On the third day I was scheduled to work for 10 hours of duty and six legs. I made it to eight hours of duty and five legs before I was forced to use the fatigue policy and end my trip. Multiple incidents on my final leg were evidence that I should not be flying. I was the pilot flying on the final leg. Amongst other things; I tried to descend to 5;000 ft when the aircraft was already stabilized at 5;000 ft. I asked for the approach checklist after already completing the approach checklist. I had to confirm with the pilot not flying multiple ATC calls immediately after we received them. Most of all; on final approach; my attitude toward finishing the trip was that I just didn't care what happened; I just wanted to be on the ground in bed. I could have completed the trip if I didn't have a circadian swap right in middle of it.
