Well, being a guy who travels a lot, I can tell you that the 3 hour thing is not mental. Im not saying I cant function. We all can. And the change is minimal. But its not just a mental thing. The way I like to tell people about it is,
-You wake up at 6 am to get ready for work on a normal day (example, could be 8 whatever for you).
-You go to bed at 10:30
Now, when you fly to the east coast, its 10:30 there, but your not tired. Why, because its really 7:30 at home. Your body doesnt just see a clock and readjust. So chances are, you stay up, probably midnight, maybe a bit later. Sometimes you dont even want to, but you cant help it. Hotel pillows usually suck too and I always forget to bring mine with me. Now you wake up at 6 am (3am at home). Your body is dead tired, because even if you got 6 hours of sleep, your body internally still thinks its around 3 am. You hurt. You take a cold shower just to see straight. You drink the shitty as **** hotel coffee. God that coffee sucks. It sucks so so bad. But you have to drink it, because making it to the corner cafe wont happen on your current energy. By day 3, your starting to feel comfortable sleeping the correct times, you wake up with enough energy to not need the shitty coffee. Now its time to go home. Now your falling asleep during dinner time. Wife is mad at you.
And KC, flying out for a thursday game is a horrible idea. It negates necessary practices. Flying out friday is already a new trend because of the acclimatization. Pete just started that last year. They literately practice friday, then head for the planes.
