Narrative:

This event occurred on the second day of a 3 day trip with more than 21 legs, and 3 12-hour duty days. I'm also a reserve pilot and have no opportunity to establish a diurnal cycle. I was very tired and probably should not have been in an airplane, but this is considered normal in the commuter airlines. We were cleared on the coatt 3 arrival to iad. As we crossed flat rock VOR, we failed to turn on course. At the same time, we were descending to 8000 ft MSL when ATC questioned us about our course deviation. I was very distracted and failed to leveloff at 8000 ft. I caught the error at 7600 ft. I feel reduced rest and no diurnal cycle contributed to this event.
