Tangentially related, but i have taken to sleeping twice per day for around 4-5 hours each very well. I have adhd and at some point during the day I will just mentally crash, in the past I sometimes fell asleep sitting up somewhere (rewarded with wild neck pains of course).
Since deliberately taking a sleep during the day that has been much less of an issue.
