@nolan You too huh? That kicked in for me when i turned 30. Its bizarre how changes like that kick in at biological timeframes like a switch almost. it becomes all or nothing.
in my 20's sleep deprivation was so common i almost championed it (out of ignorance i assure you)
A nice cup of hot tea and a book do wonders for that though. And i applaud your 10pm lights out routine. Thats a good one to adopt.
