I have smoked pot every time I want to sleep for at least 25 years, never while I want to be functional. I cracked my head about 25 years ago and I tried everything but going to a place to watch me sleep. Kaiser suggested I get a pot card and the first time I smoked I fell asleep standing up leaning on a door jam. I had only slept 8 hours for a little over a week, and I was going nuts. I tried one time going on vacation to a non pot state, I ruined everyone's vacation because I had to keep getting up to slow down my thoughts. Everyone cut their vacation short and we all went home. I have not stopped since, it was horrible.
