You are doing awesome! I just know how hard the lack of sleep can be. If you do want some advice, you could add a question to one of your threads and ask an expert to take a look at your spreadsheet and try to help show you some examples of nights where they would have felt it safe to go to bed earlier. I’m no expert (sorry) but Petty does seem to be having pretty nice flat cycles. In the last week or so, she seems to consistently have her low point of the night at or before the +6.
Again, absolutely no pressure, the data you are getting is fantastic. Just make sure you take care of yourself too!!
