You would think staying up for 36 hours would get you to sleep because I become quite a zombie when I go too long without sleeping and eventually just crash out. I have done a 3 day work shift one time and literally slept for 36 hours afterwards. The snooze button trick never works because I never hear it when I am asleep because I sleep like a log. I know you battle and have tried all the tricks in the book to sleep and hopefully one day you find a technique that works.
