Narrative:

I departed ZZZ IFR on my regularly scheduled run to XXX airport. The trip takes about 1 1/2 hours in the baron BE58. I fly on most nights. During the previous day, I had slept my usual 8-9 hours before checking in with dispatch at XD45. My run starts in ZZZ and leaves for YYY, VVV, ZZZ, XXX, a 2-HR break, ZZZ, VVV and a return to ZZZ by XA30. I depart from ZZZ, GPS direct, and climbed to 6000 ft and turned the autoplt on. In the vicinity of abcde VOR, I got handed off to ZZZ approach. Then about 90 mi out from XXX I got handed off to ZZZ center. After having flown in some of the most congested and active airspace in the country, I leave for a trip into parts of this country where often you check your radio, at night, because there has been nothing, but silence for the last 30 mins. Approximately 40-50 mins east of XXX, I dozed off and feel asleep! (Consequently, when the ZZZ center controller tried to get in touch with me for a descent and a handoff to XXX approach, I did not hear him. I abruptly woke up right on top of zzx international airport. I had overflown my destination by 15-20 mi! ZZZ center had obviously informed XXX approach about the situation and I do believe they contacted the chief pilot of my company. On the ground we had a long conversation about how lucky I had been and how I have flown this route for 2 1/2 months and I know it very well. And on this very calm and beautiful night, I let my guard down and I let complacency get the bet of me. As I was leaving ZZZ, I set myself up to a relaxing flight where very little would be required from me in order to get to XXX. A simple few exercises consisting of stretching my hands, arms and legs would have kept me from falling into the trap. And even though I have flown this leg many times, there are still things I can do to keep my head sharp.
