Narrative:

I arrived ZZZ at the hotel at XA00L after reporting in ZZZ1 at XQ45. I slept until XH00. I went back to bed at XP00 to try and sleep to prepare for an XA15 am show time with an XX30 am van at the ZZZ hotel. Sleep was unsuccessful until approximately XR30 and awoke at XV45. A 12 hour duty day awaited me which involved 4 legs; with a release time of XM30. During the first leg of the trip; I caught myself making little mistakes. During the second leg; I started feeling the effects of fatigue; including nodding off and misprogramming the FMS. In the interest of safety; upon an uneventful landing; I notified crew scheduling that I was removing myself from the last turn due to fatigue. Arriving at a hotel and then leaving exactly 24 hours later does not allow the human body time to adjust from daytime flying to nighttime flying. Sleeping when you arrive at the hotel; and then trying to sleep for another 8 hours; after only being awake for 8 hours; does not work and never will. Suggestions: closer cooperation between crew planning and the scheduling committee to ensure flight crews are properly rested during pairings.
