I spent the past month travelling, sleeping someplace new almost every night. Did not get used to it. I had maybe 4 hours of sleep per night. Still, I was awake during the day and I had more functional hours to use for exploring, so it didn&#x27;t bother me. Last night sleeping in my own bed was the first time in a very long time that I&#x27;ve had a full 8, but I don&#x27;t notice any cognitive difference.
