You are so right on all the things you listed. I am so exhausted sometimes from trying to make myself sleep. I am not sure what a “restricted sleep window” is but I am willing to try anything to get some energy. If it is night time I try to go back to sleep, if it is after 8 a.m., I get out of bed. Last night I got 6 hrs. (4hrs and 35mins and 1hr and 24 mins). Would taking a nap during the day help with the tiredness? So exhausted.
