When I was living as an English teacher in extremely rural Japan, I went home to visit my friends one summer. I had a great time, ran around like a chicken with its head cut off for two weeks barely slept at all… and then headed back to Japan. After flying for approximately twenty-two hours including layovers, I arrived back in the country in the afternoon of August 5th, but it was still a huge trip to get from Osaka to my island… and I had to work on August 6th. It was vital that I be there because another nearby island was getting a new English teacher that day, and as the person most fluent in both Japanese and English anywhere in the area, I had to be there to act as translator.
As soon as I got through customs at the airport, I ran as fast as I could to the train and took a series of local and bullet trains to get home. I ended up in the port town closest to my island at 12:30 in the morning on the 6th.
Now, remember how I said it was extremely rural where I was? Well, there weren’t any hotels anywhere in the area that were still open and accepting customers that late. So I left the train station, went down to the port, found a nice bench, and lied down. That’s where I got my approximately four hours of sleep that night… though it wasn’t really sleep at all.
At oh-dear-God-that’s-early in the morning, I got up, ran to buy my ferry ticket, quickly changed into work-appropriate clothing in the port restroom, and then hopped on the boat. Forty-five minutes later, we docked not at my island, but at the big one nearby that had a road that connected to the (other) mainland.
It was there that my supervisor met me (he had come over to the island from another ferry just a few minutes before), and we packed my stuff into the trunk and then drove two hours south to the little regional airport where we were meeting the new teacher. Thus, immediately after travelling/sleeping on a bench outside for approximately forty-three hours, I went to work and spent the rest of the day as both tour guide and translator.
It will suck to get back from your honeymoon and then go back to work, but it is doable! Like PPs said, caffeine will be your friend.
