I used to have trouble sleeping while travelling, but after I started the keto diet and began using sleep earplugs, I no longer experienced those problems. I am now able to achieve incredible sleep in short durations. But I really understand the issue with sitting all day, needing non-stock seats, and being able to change up leg positions. Compression socks help to a point. Connor and his swollen feet are something I recall.
The navigation through the cities was fascinating; it reminds me of the time in Vietnam. Just chaos with machines.
