I keep my own work hours and schedule my work around deadlines. If I have a deliverable Friday afternoon and I'm going to sleep in the morning, I have to get it done Thursday night. The beauty of this for me is that I know what my productive hours will be and I can work during them, rather than shoving work into a specific time frame regardless of my circumstances. Things like going to the store I can do any time of day, pretty much. With things like doctor visits or work meetings that happen in the daytime, I'll stay up late or get up early as necessary. I can usually get back "on schedule" very easily just by going to sleep when I feel tired and getting up when I'm rested. I'll usually go to bed and get up close to when I usually do because of where my circadian rhythm is, and even if my schedule moves a few hours one way or another, that doesn't have a detrimental effect because I'm so used to the lifestyle. It's pretty consistent. I used to track it on a sleep app but I've gotten out of the habit (it's not been necessary). I don't think there's been a month recently where I haven't completed a full rotation. Back when I was tracking data, I have graphs of my sleep schedule making a diagonal pattern across the month. It's very reliable.
