sodapop: PS: Murexway, why did you change your commute policy only after upgrading to the left seat? All of us should be "fit" to fly and I'm sure you wouldn't appreciate having your FO add to your workload by doing the same things you mention your tired CN did.
I didn't change my commute policy. When I was an F/O, I bid early trips, came in the night prior, and stayed in a hotel room. I found I was more rested than commuting in early the day of the trip and grabbing a "day" room at a motel like the tired captain usually did. The only change when I upgraded was to buy a second home in my crew base city, which was quieter and more comfortable than any hotel. Thus, I was always fit to fly. Commuting was my choice and I didn't feel that it was fair to my fellow crewmembers (cockpit or cabin) to arrive for work tired. I also felt that it was better for my health to avoid the physical stress of excessively long hours between sleep periods.
