Believe it or not, drink a lot of coffee throughout the day and you will be tired when it wears off. I drink coffee up until the time I go to bed. Eat a few bites of some magic mushrooms, just a microdose, not too much before sleep. Also, the lavender spray works great, especially with a few Natrol Melatonin chewy gummies. Do exercise in the morning every day for an hour, like biking, that will wear you down and you will be tired by 11pm probably.
If you really want to doze off, take half a Zanex, or an Ambian. I took Ambien and my friends would bet me I could not stay up, that was for sure. Just don't mix alcohol with Ambien cause it will make your memory disappear. Once I did that and kept meeting the same people over and over every 5 minutes. lol
